Atomic, the one on Adern.com is JIRC and its a commercial app, but I actually know of a free one that is better called pJIRC (gave it to Red a while back, Adern should see an upgrade soon). Planetz could easily use it for a page (I'm familiar with customizing it too so could setup the colors etc.)
I've got one at kief.net/irc/ but that is tied to my channel so here's a version that will dump people into the right channel:
http://www.kief.net/irc/planetz.html
there's a nickname box in the lower right or you can change nickname by doing: /nick (nickname)
This client supports multiple channels AND multiple servers.
Counterparts: asking if IRC is safe is a bit like asking if web browsing is safe. There's always going to be security holes in computing. With reasonably up-to-date software and some forethought about your actions you're usually (hopefully) fairly safe. In #pulsarmusic you should be fairly safe assuming you don't wander around EFnet clicking links randomly and use one of these clients:
mIRC (Shareware with no expiration: windows)
X-Chat (Free except the windows version: windows, linux, bsd, OS X [aqua & X11])
AKWA IRC (Shareware: MacOS X)
Snak (Shareware: MacOS X)
ShadowIRC (FREE-MacOS X)
IRCle (Shareware: Classic 68k, Classic PPC, and Carbon/OS X)
BitchX (FREE: Command line app - many OS's supported)
