I'm planning to set up a meeting on IRC with several people to discuss ideas for a game they're making.
Sad thing is, most of them are in different timezones and only available at certain hours.
What I'm looking for is a piece of software that I can use to enter all their timezones and the times they're available at, to determine the best possible moment for them all come online.
That's a pretty long description. I don't know if anything like it exists and my googles have turned up nothing. I'm probably not describing it good enough for google to make sense of it.
