You can end up with a goodly number of partners if you're a goblin like me, flitting from other peoples' request threads rather than making your own. While you end up with some people ghosting you still, you can usually find partners that suit your taste very well if you get good at introducing yourself and providing spins on ideas that other players have; usually, people have RTs that are strong enough that you can tell what tone people like and how to strike a good balance straightaway.
The best skill I've ever learned on boards like this is flexibility. That's the best possible way to meet people and get along with them, since the PbP nature of this site makes clicking well extraordinarily important. It sucks to talk for a week and have it go nowhere.
