So, I didn't see a spesific qusetion form but help seems good enough.

I am wondering if its alright if my character owns a inn. Yay? Nay?
P.S. I was thinking of calling it the Castel Wall inn.

Your character can own an inn, but it won't be an actual sub-forum. In fact there is another character on the site who owns a Tavern and Inn. If you wanted to have the inn be an actual forum you would have to buy a house and call it an inn, in which case you'll get your nice little Castle wall inn in the homes/character houses forum.

So, to clairify, I can start out owning an inn and when it gets enough renown(money) I can make it a sub forum under houses?

That's the jist of it. ^_^ Beware the local pyromaniacs though.

Thanks, I'll keep myself in check...er... I'll watch the local pyromaniacs...
