Since you clicked the link to this FAQ I assume a Spoiler Alert is not necessary here. So here we go, the new hidden command added to Messenger Plus! 3.51 is /community. Stop reading here if you want to see its result for yourself first, because what follows kind of gives it away.

In the picture, from left to right, you see KeyStorm, Apatik, optimism_, Millenium_Edition, wtbw, Patchou, Fraisie, TheBlasphemer, CookieRevised, MenthiX, and Sunshine. It was taken in Paris during a meeting organized by Patchou. And yes, KeyStorm's face is Photoshopped since he had to leave early and didn't originally appear on the particular photo. More photos of the meeting can be found here, but don't expect me pictured on any of them. The reason? Two "obligatory" christmas parties the day of the meeting (December 27th 2004) :(
