Well, I undrestand most of the abbreviations here:
highlight it & right click go to copy click & then have PT signed on & then to your user cp & edit & paste into your signature, But plain english would be easier.

When I get to the PT part, I have to guess that stands for Pet Talk? The cp, edit & paste, I got that part, but what is the "signature" that I am supposed to be pasting into? I am not seeing any place that indicates where a signature would be located.

I have tried the copy and paste route from my own photos, but the "paste" part comes up blank whe I go to put it in the message. Says I can't "You may not post attachments" anyway.
