If you're going to do something like that, the key paragraph might as well be:
To remove the suspension, click on THIS LINK. You will then
be able to log in normally. If you have forgotten your
password, the link above will offer to e-mail your password
hint to you, or send you a new computer-generated password.
The "THIS LINK" would contain a randomly-generated code of some sort. This keeps people from having to deal with weird "add this to your username" type things.
There is no sig.
