I've just downloaded the 0.20 archives, installed and configured them. After a bit of teething with setting up a non-standard internet provider, I'm online and testing.
I've been using FreeNet for almost 2 years and this is the first time it's actually worked fully (ArcWeb was the only one that worked before)! I'm *very* happy to have the full range of internet tools now.
A big thanks to all those involved in the project - I'm going to spend the next few hours playing.
