http://www.mechapinoy.net/forum. I know MatX has issues with this forum (it's my home forum, since I am a founder of the original Mechapinoy Mailing List that was an offshoot of the original international Gundam Mailing List more than a decade ago), and I agree with him that sometimes, n00bs (different from newbies) do get rough treatment. However, as long as you read the rules of the forum beforehand and spend some time observing the way to properly interact within it, interacting in Mechapinoy can be a pleasant experience.
There are many tutorials in the forum, ranging from spraycan usage, handbrushing and airbrushing to sealing, modifying and scratchbuilding. There are also threads for works in progress, and finished kitbuilds. Some of these are from past winners in national and international competitions, with many of the others being from extremely talented builders (some of them practically professionals).
Mechapinoy also has the monthly MechaMeet, where people can trade or sell kits to each other, socialize and work on kits (and get tips on how to work their kits).
Finally, Mechapinoy is one of the main fan organizations connected officially with Bankee, the official distributor of Bandai (gundam) in the country. As such, if you've seen the Gundams on exhibit in the various malls...those are probably from Mechapinoy members (I'm an exhibitor for most of the events).
We hope to see you in the forums, cheers!
