Hi, I was wondering what facilities xenforo has/is iminently due to have for controlling access to areas of the board. The board I intend to launch will have a bunch of subforums for specific books(not my own products). I want to be able to restrict access to those forums to people that own the product concerned. For example - can I set passwords to a forum (say the first word on page 5 of the product) and members have to enter that to prove they are a purchaser and then gain access to the forum. If so, will xenforo remember that they have provided the correct password - or will they need to provide it on every visit. Failing passwords like that, I assume there is a permissions system built in to the software, manually setting up permissions for all the users would be too impractical, but maybe I could have a cusotm page that lists the subforums/products - with a box for each where users can enter the 'first word on page 5' or similar and then submit the form - which would then update that users permissions for any subforums for which they provided the correct answer. My PHP is next to nil, but is a system like described above something that would be a relativitly simple thing to code? I assume it would just be a matter of checking the answer is correct then updating the mysql record for the members access permissions? Any advice about xenforo's suitability or specifics about how I should achieve my aim appreciated Thanks!
