there is a version for 3.5.x but it costs 25$ from the coder/company who did it and from what the coder told ME its even better than the old version with MORE options and NO bugs...
i know im a new poster too but i have talked with the owner of the new script on vB.org
his name on vB dot org is "Psionic Vision" or something of that sort...
i am thinkin i might just pay the 25$ instead of waiting another year before i find someone who will decide to take the ten minutes to change over the coding to a 3.5.x compatible version of RBS...
