As designed Signature "Maximum printable characters"

[Claudio]

If I set to yes the "Edit signature" option in the usergroup permissions and the "Maximum printable characters:" is set to 0, I get a message saying that I don't have permissions to access to the edit signature page.

This is confuse because actually I have permission (because I set the option to edit my signature to Yes). My suggestion is to show a message that I don't have any "Maximum printable characters" allowed.

But you wouldn't be able to enter anything in your signature so you effectively can't change it. As such, it was done intentionally.

The distinction may be useful to you, but not for an end user.
