D o not mass version, mass ping, mass any thing. I'm new to this channel. Well, the best thing to do is to hang out for a while and try to get a feel for what the channel's like, who the people are, and what's being talked about at the moment. Jumping in with non sequiturs is ill-advised. What they say, goes.
Most irc clients indicate who in the channel has operator status.
Read the manual or help files for your particular client to find out. There are a number of places to get software for your Macintosh. See the Info-Mac Mirrors and Recommended Software sections of this site. That's not right. You will not get a copy of any piece of commercial software from anyone on the channel.
