about Psi Jun 2011

Installed Psi today and got to say that the low memory impressed me. I like simple and plain IM's so I give Psi a couple days to convince me. Minus is the website, although the start-page looks nice smiley packs or other stuff is nowhere to be found. I got the smiley packs through google.
