BUG - Unregistered Users Creating Tournament SQL Error

I've tried creating a tournament as an unregistered user (for some reason unregistered users still see the "Create Tournment" link...). What happens after you click on the Create a New Tournament link is this:

There is a SQL error.
You can contact the board administrator by clicking here

We apologise for any inconvenience

Is there a fix for this, or at least to hide the tournament creation link from unregistered users?

Yes, this is already fixed for next release v2.6.8+

Cool, when's the next version due? If it's far away, can you provide a fix for now?
