I LOVE your plugin and functions as it should... but can you suggest a hack on making the error message actually appear like it's coming from the site instead of some out of site error message lacking the site wrapper and site css look?
I added the following bit of code to at least send the user back to the previous page, but I really want the message to appear that it's still part of the site.
Suggestions... hacks... brilliance? Thanks in advance...
