You can bitch about someone's "professionalism" here when you start paying them per-post. Otherwise, it's a hobby they are fully entitled to drop out of for some time if needed. You can go fuck yourself if you think you're allowed to do anything more than think someone's rude when they don't respond to any of your PMs.

Ahem. Back on track for me.

Once thing I've noticed(and hate) is that sometimes, people simply WILL NOT react to anything other posters' characters do. They're just off in their own world, leaving other characters to scratch their heads in confusion. It's hard to build character relationships if a character outright ignores everyone else. Almost as bad as the posters who write characters that don't actually do anything(fucking "loner" characters...).
