Text on registered users only sign in prompt

If enableNewRegistrations is false, and we have a non logged in user viewing a registered users only forum, there is a sign in prompt which in english reads:

Only registered users are allowed to post here. Please enter your login/password details upon posting a message, or sign up first.

Of course, it is impossible to sign up by following the sign up link.

For my purposes, a quick hack of the language file suffices as all my forums are registered user only.

I wouldn't say it's a bug. Just modify your language pack, and you're done. That's the correct step.

In miniBB there are tons of options, if we will program all of them in the language pack, it will be dramatically reduced in size. If you have some custom option, just modify the language pack on your own. It's the way that thing is planned.
