Oberon and Vega, ugh.
I always check offtopic first, as it's basically a large forum populated by PSO players = automatically interesting, for the most part. I always find something interesting to respond to there, and, unlike other large gaming forums such as uh, GAMING AGE OR GAMEFAQS, COUGH, it's not populated by thousands of fanboys, trolls and uneducated rumor spreading sons of motherless goats. Lots of cool people in Offtopic.
The main forums on the other hand, I tend to mainly reply to newbie questions if/when no one else has in a thread, or add my two cents to any other topics.
Otherwise, I check these Rants forums occasionally as well as Fresh Kills (for a good laugh
), and very occasionally the other forums. 'Cept for the admin one, of course.
