So most of you probably already know about BoolProp, but in case you don't, BoolProp is a simming forum for fans of the Sims! Which includes ts4!
BoolProp is a great place for you to get exposure for any Sims stories you might be working on, as there are plenty of forums for various sims stories.
While there is a focus on stories, there are also lots of fun events/competitions and a great, drama-free community overall (plus I'm a mod there sooo ;))
Check it out! (please?)
