SMS signature - how to?

I want to add a brief signature to SMS messages (just my name and website) automatically. I do not see where can I define that other than in individual SMS templates? tx

Right now there's not a way to do signatures on SMS. You've only got a couple hundred chars so it'd be easy to eat that up -- and you can't put in logos etc like normally go in footers.

If you want to hack it:
- Add an account level custom field (text type, not rich text)
- Enter your footer info there
- Reference that field at the end of each SMS template
