in reply to Meeting & conference announcements (updated with suggested guidelines)
Some events are announced here (in Perl News, as has been pointed out) because somebody felt strongly enough about the event to announce it, and remembered good ol' perlmonks.
I cannot remember a single instance about somebody complaining about a perl event being announced on perlmonks, so my advice would be "do it".
If, one day, we have the problem of having too many announcements on perlmonks, I suggest we start the discussion again. Until then, don't hold back.
