I'm active on vogons.zetafleet.com as well.
abandonia is my "second" love after vogons.

Been on two forums earlier va.tik.lt and CGA.
I found abandonia earlier than CGA, but thought it's forum was too complex, heck, I came in. :D

Apart from Abandonia, I appear here, here and here, but these are p2p community forums.
:bye:

More than 3 :sneaky:

I'm currently active on 2 forums, but I was member of many more. (and still I am)

I also used to moderate/admin some forums, and for a year or so I hosted my own forum.

I used to be really active on the Sierra Communities Official Quest for Glory board, but there was a falling out there with one of the moderators...(ended with me being banned, but him being removed from moderator)

Also for awhile in fourth grade, I was really into this online wrestling forum. Has anyone else ever done those? WHere you make a character profile (moves, height, attitude, etc.) and then you role play interviews about your upcoming match and whoever has the best usually wins the match in an e-mail they send out with the fight's commentary. It's kinda hard to explain, but they were fun...I enjoyed them (if you could find one that was fair...my brother and his friend ran a really smooth one once called Sunfire)

Active here (now a mod), www.megamassmedia.com/index.php and Tre 4 (theres a link somewhere in multiplayer)

I`ve only been a member at one forum before abandonia.
Portent forum. (A boardgame site, mosly warhammer related)
:cry: Sadly the portent forum was shut down a couple of months ago because of economic reasons and the fact that it took up to much of the creators time.
Portent, you will be missed... :kosta:

Humm...

EDIT: Gamestar.pl forum - I am sort of self-appointed Arcanum specialist there.

That's 10 boards before Abandonia, and these are only those I remember. There are probably about 2 or 3 others where I did register and forgotten all LOL about it.

I'm also active on Staregry.pl , it's a polish abandonwere site :D
