It should be no problem. Just go to "Settings" on the top right of this screen. Then go to "Edit Signature" on the left of the next screen. Make it what you want and then click "Save Signature." If that doesn't change it, let me know or PM Chip. Members are no longer able to use HTML or to edit font size. I don't think you can edit the color either.
Thank you. Got a bit confused by the VB interface. Assumed that there'd be a little edit icon next to the sig field in my profile as there is with the bio information. Sad thing is I've modified it before. I'm getting old.
