First and foremost, fora is the pluralization of singular forum. Since we've got that base covered, what other fora do you read?

I read NeoGAF. I used to post there too, before I got banned three times in a row for trolling people and backseat modding the mods.

The only other fora I read are Slashdot and Youtube comments. I always post anonymously on Slashdot because it saves me the trouble of having to register. That's why 4chan works great too.
