I noticed you signature has the word "FONT="Comic Sans MS"], it also needs the word [/font] at the end of it so that the first "FONT won't show. Those are instructions and you must always have a begining and an end.
If you want your signature to look like this,
Lynn & Twinkles 
copy this:
[FONT=Comic Sans MS]Lynn & Twinkles[/FONT] :lovewings
