"WTB/Looking For" acceptable in signature?

[jackthedog]

I tried to find it in the rules, but might have missed it, but can I have a "WTB/Looking For" line in my signature block? Thanks.

It seems kosher enough. I had one in mine for months and never got any flak over it.

Yes, you can.

Yes, you can.

Thank you!

I see it quite often enough, fwiw.
