There is an issue if you use this modification and have a password protected forum. Users write their post, click Anonymous and submit, but then get an error message that they cannot access the page (I'm assuming because the Anonymous user hasn't entered the password for the forum). They can't post polls at all because once they are directed to the poll page, they get the same error.
Does anyone have an idea for a workaround on this?
ETA ~ I tried installing this modification so that the anonymous user could be ina usergroup that didn't need to enter the forum password:
