Online charactar/rp games?

Does anyone know any good online roleplay games, I'm not looking for a specific one, like dragon or something but just a very vague one where you can make you own topics, I can't find any and I like the roleplaying because it helps my writing skill and really relievers stress. I'm not looking for one based on a specific game though, I already know about hexrpg and such. And I don't mean one with actual charactars like furcadia but one with forums.
