To sell and buy items and services with your fellow Gaians.

Can i Talk about an existing store out from the guild?
Yes, but use one thread only and no advertising it.

can i advertaise my shop in the guild?
Yes, if you are advertising a shop within the guild, but if not, no. That would be considered spaming. But if it is in your sig, you don't need to worry.

No. Only if the creator gives you permission for that.

What happens when I dont need a forum anymore?
Pm lylatay and she will delete it for you.
