Did you place - in a new message - a mark before 'Rich text'?
If not there will be a not formatted signature send.

Hi, I'm trying to set up 3 signatures to insert 3 different web site links, Although I thought I had it all set OK, when I try any of them on send I get the same signature whichever one I select. Any suggestions please?

Make sure you are adding your signature to the appropriate variant.
Pegasus Mail has four variants of each signature:

Local address, plain content
Local address, formatted content
Internet address, plain content
Internet address, formatted content

The variant shown when you enter the signature dialog is "Internet, formatted".and this is the one you want to use when sending the "Rich text" links.  If these are simple URLs though then you probably want to use the plain text version so you could send the same signature to both plain text and rich text messages.

Take a look to:

I have followed you advice most carefully and I though everything was OK when I tested it, but today when I booted up and tried to send a message inserting one of the web addresses I set as a signature yesterday, nothing, I tried all 3 signatures, all empty, I went back to >tools>options>signatures and everything is exactly how I set it up, but cannot insert them into my outgoing message, What am I doing wrong?
