...and with those words, I have stepped into the Idolm@ster fanbase, with a loud thud...
Ahem. Enough goofiness.

Name's WarOmnimon and I will not be afraid to admit that I am a bit new to this particular fanbase, but have been an Idolm@ster fan for a few months now. I also happen to collect virtual pets, mostly Digimon and Tamagotchi - I have quite the collection, including many Japanese versions.
Now to answer Roninantor's questions...
Q: How did you come across this site?
A: Mentioned it above, was looking for information on the series and came across the site's Wiki.
Q: Why did you join this site?
A: For the fanbase.
Q: Do you play it?
A: I'm planning on doing so once again very soon - played the PSP version briefly but didn't make it too far in my first run.
Q: Who is your fave idol?
A: I have three. In no particular order... Makoto, Haruka, and Takane.
Q: Why is your username "WarOmnimon"?
A: "War" from WarGreymon, and "Omnimon" is the english dub name for Omegamon - both are Digimon. Been my online handle for years now, and I don't see it changing any time soon.
Q: What are you in to right now?
A: Idolm@ster (Of course), Digimon (That's Imperialdramon Paladin Mode as my avatar by the way), and anime and tokusatsu in general. I also happen to be in my third year as a power lifter in the Rhode Island special olympics.
Q: What is your motto?
A: Don't have one right now.
Q: Who's your favorite singer(s) right now?
A: JAM Project. Wings of the Legend is epic.
Q: What are you up to right now?
A: Not much, except filling this questionaire out.

Q: Do you have any expectations from this site?
A: Not directly as of right now.
