The title says it all: PaintChat sucks and I'm fucking tired of dealing with the broken, outdated, outmoded pile of fail. For some fucked up reason there doesn't seem to be a good replacement that anyone knows of that isn't either some paid piece of shit corporate collaboration tool (that still doesn't do what we want) or is a fucking hypothetical ("We've got a Java-based PChat-esque application but we haven't got a public release yet and our last update was 2006!").
So, post your suggestions here. If someone just knows of a modified PChat 3.66 that has working admin functionality and doesn't, you know, shit the bed for no reason at random intervals, please post that as well.
