How do i delete my old signature and put a new one on. When i delete it and add a new one in it just ignores it and keps the other one.

highlight the sig bit you want to delete and press the backspace its usually how it works

That does not seem to work

You are saving your changes aren't you?

No the only options i get is reset or submit.

And are you pressing submit?

Click PROFILE above.

Edit the sig as you require.

Click Submit.

done that several times it just comes back the same

Just tried it myself and same result... No change?

'Tis true!

Serves you right for putting stupid signatures on then
