Am I allowed to advertise something off site? For example, an Etsy account? Thanks :)

I suppose so. I know a lot of people have links to their tumblrs and deviantart accounts. You might want to double check with someone else though.

I don't see anything against it in the rules. (assuming your not advertising a different virtual pet site, or anything illegal)

No and no to both of those. :) Thanks you guys!
