there was a time when i had a go at doing something similar.
http://www.dbtoolz.50megs.com/
Many years ago i had a site called dbtoolz (major dbc days)
anyway a lot of wombat crap went on between blitz and darkbasic between the programmers.
it was neck and neck for a long time until blitz went a bit slower in development.
Many people back then were indeed amazing keyboard cowboys.
aristid used to amaze us with stuff, a 14 year called magellen would astound you with stuff he demonstrated. the names go on and on.
some are still here, gday wolf,las6, tdkman etc.. forgive me who i missed.
If i recall as well at the time the german programmers had it really down
with a few demos that rocked the house.
The point being is that it is possible but it will take up valuable game dev time.
It takes a unique person to gauge the whole community nowadays as its easily 5 fold in size, as well as target a website for use away from this forum.
We used to have a few forums and that divided the community for a while,some bridged across, some stayed on one forum, the alt forum went through a few Phoenix bursts after the first mystery bomb hit that community.
people are wary of leaving here and losing connectivity with the products community forum.
I guess when you want an answer solved you chose the smartest group in a forum which can make it so attractive to visit.
I say go for it, but keep in mind whats ahead for you if you build an unofficial repository / forum
dont be discouraged if it doesnt pan out.
