I signed up, I like the idea. I really really think you've done a great thing trying to create something like this (and I love the map) but..
Drupal (the scripts powering the site) seems a bit... well... erm... how do I put it delicately?
Do you use this one at work? Was it the first you came across? I am just curious.
vBulletin (what's used on EAB) or phpBB are my faves when it comes to forum related activity. But I would imagine you are really trying to get away from a forum style site. No? I mean why duplicate the functionality of EAB, Amiga.org and Amigaworld.net etc.
I look forward to seeing what happens.
Personally I'd like to see some UK based activities, bar meets etc. Perhaps some recommended shops & their locations (although they go out of date fast) times & dates of good car boot sales perhaps?
