My hosting company is currently installing a new forum platform. In the past few months we have been experiencing a large amount of spam on the NRF and we did not have the proper tools to fight it. After doing some research, I decided to go with Vanilla Forums, which is a very clean and intuitive solution (check it out at http://vanillaforums.org. The most difficult part in this transition will be the migration of current database (topics, usernames and passwords). I will update you as I get more information on the progress from my hosting company.
Thanks and Happy Holidays!
