I have a ticker but when I try to sign in my email is not recognised. How do I fix it?

A My PitaPata account is optional, you don't need to have an account to create a ticker on PitaPata. More about My PitaPata accounts.

If you just want to remove your ticker from where you are using it, eg. your email or forum signature, you do that through that application. For instance, to remove a ticker from your Yahoo signature, you would log in to Yahoo. There are instructions for other applications under their respective headings in the Help center.
