It's not particularly 'easy' to do, you'd have to either echo the /names reply to the channel window - which would be ugly, or write it to the logfile yourself - which wouldn't work if you have the 'Lock logfile' option on (which is on by default I believe). Besides, the entire logging sytem could be scripted if someone wanted to, that doesn't mean it shouldn't be built into the program.

Spelling mistakes, grammatical errors, and stupid comments are intentional.
