- Thats good. :-) An active file for a full feed has about 5,000 lines
- and can be close to 200k.

- The active file will get changed whenever there's a newgroup or change
- message for any group in a hierarchy you get. Here, that's several
- times a day, and thats for only a partial feed.

- Certainly.

- I'll complain if something has to lock the active file, but I don't
- mind if you keep a copy updated through notification and do whatever
- you want to the copy.

- Thank you.

- You could always email Geoff Collier (sp?) for information about his new
- format. I don't have it handy but you could try Henry Spencer instead
- at henry@zoo.toronto.edu

-
- Great. I hack sources less than I think I will, and I think I won't
- very much, but I always like to have them. :-)
-
- P.S. This article was posted with Arn 0.72. I haven't found another
- Amiga news reader that works well enough to switch to yet.
