Please help me out. I’m trying to add buttons to my signature but I could only add one. How do I add multiple buttons to my signature?
You add them like you do pictures that need to be embedded. If you add them to Flickr or another site that allows hotlinking you should be able to do it.
Please note: Keep the size of your signature, including buttons, fairly small. We’d also prefer you not use anything that is distracting such as lots of bold text or blinking buttons. 
The new guidelines are now included with the Forum Guidelines.
