Advertising in signatures?

Am I allowed to advertise in my signature?
I was hoping to put this..

All breed dog rescue, positive training, custom id tags, natural grain free treats and grooming!
and my email.

thats all.

Sure, it's fine. We give a lot of leeway here. We (the members and mods) can differentiate between a real person who participates with the forum and happens to have a link in their signature from a "signature spammer" who simply posts "I agree" or "Nice photo" on hundreds of threads just to get their signature out there

On a side note, I saw you were "moderated" earlier. If you see that message, just PM me or one of the other mods and we'll be happy to check it out and get it approved before it gets accidentally deleted in a spam sweep.
