IRC #javascript chat snippets The wisdom of the really wise crowds.

Privacy concerns Only a sample, no code written. Aim: To try to manage tons of useful info in IRC chats. Nothing logged yet for this, but do see "IRSeek" Names replaced with random names (similar can be done for timestamps, signatures, “away” messages) . Anyone should be allowed to opt out. “ Chill effect”? Knowing the possibility of logging might actually reduce junk on the official channels Newbies might get scared off initially seeing nicknames on presentations - just till it becomes a routine - like Facebook and MySpace. If ops don't like it, it isn't going through anyway :-)‏
