- .... Over the pass 7 or so years i've been "around" the h/p
- scene, i've seen alotta changes.. for years i saw the europe scene
- boom outta control and i saw bbses here that went from 500 new
- messages a day down to 10 new messages a day over a weeks period..
- things are wacky in the world.. the underworld has so many benefits
- for those that dwell within.. however there are downfalls. these
- include annoying irc kiddies and pompous eleetists.. essentially they
- are just kids who want not only an identity, but THEE identity.
-
- well, i'm bored with the whole rat race aspect of the scene..
- i've always just been in it for the "being in the know" aspect of it
- all.. and basically that is what we all need to realize; if you really
- want to be a part of any society, you must respect it and hold a
- decent understandin of how it works before you dive in and try to act
- the socialite. slowly you will become part, and you will be in the
- know.. in the chicago h/p vicinity.. i'm one of the sysops of
- apocalypse 2000.. the board has had good times and bad times.. right
- now it's going thru a pretty decent time message activity wise.. but
- the activity pertains to things not all too underworld related..
- about 97% of the original h/p affiliated users we had ceased calling
- since the board first went up about 5 years back. i don't know if
- chicago peoples tend to have identity crisis' and just keep changin'
- their handles or if people are just dying off from the scene, while
- the new kiddies enter after catchin the movie hackers..
-
- all i can say is.. i'm glad i've stuck around and although the
- scene isn't all that active in chicagoland for it being such a large
- city, i know i have benefitted from being here.. and i basikally wrote
- this just to tell the chicago scene to respect what you have and
- utilize it.. many h/p peoples i know aren't so fortunate.. being in
- little hick towns and easily findable. we have so many resources in
- chitown it's insane to think so much of them are going to waste. keep
- with the scene, keep the boards alive.. keep the convo alive.. and try
- to be as active as you can or you may just see big brother win. yeah..
- i'll stop bitchin' now.
-
- what we got for youse in dis here mag.. is good stuff.. for
- starters.. we have a mondo-huge acronym list.. in relation to
- telephony, radio, computer, and other interesting items to read
- about.. i feel like we've become a huge glossary/acronym mag..
- you'll understand what i mean.. in the next few issues i have a
- 500k cellular glossary i'm going to release.. anyways.. we then
- gots a huge cdma glossary.. and although this does probably
- overlap with the acronym list a little.. don't cry because of some
- redundancies.. the cdma glossary is in reference to Code Division
- Multiple Access, the digital telephony service offered thru providers
- such as PrimeCo and Sprint.(ref:issue 11).. at the bottom there's
- always some news regarding technology, busts.. and whatever.. and
- then comes the bbs listing.
-
- next issue will have the bank info and recon info we promised for
- this issue.. things happened.. things are moving slow.. not good..
- but we will have them for the next issue.. of course, the following
- next issue will most likely have the phatass cellular glossary and
- we'll prolly leave it at that for that issue. the following issue
- will have a background on how to use a SecurID card and dialup and
- other good stuff too.. really.
-
- later peoples - fringe pimpin'

- Is no news good news? not really.. there is news.. but i haven't
- bothered to get it together for this issue.. however.. there is
-
- Local News <+> 10/97
-
- Jello Biafra, the main SysOp of Apocalypse 2000, has left for
- Israel. He will be there for approximately two years and hopefully
- won't get shot. Now, normally, I don't think he would get shot except
- for the fact that he is enlisted into their military. As we get back
- interesting stories from him and what not.. we will relay the info..
- however at this time we do not have any means of communication to
- reach him where he is at.. you can send him email thru pimp@dope.org
- or to subhuman or fringe on the board.. we will forward it to him as
- soon as we can.. and please.. make sure it's not something stupid like
- "hey what's up dood?" because it's not worth our stamps. Jello will
- be back in the spring for a short visit.. and we will most likely be
- having a huge gathering for this event. for more information please
- hit this site: http://www.dope.org/fringe/apoc.html, the apocalypse
- home page. If we can get a fone number to reach him at, there will
- be a teleconference set up for peoples to dialin to.
