I have 3 usergroups, with 3 poll modules. I've activated in the configuration. Each module is set up to be view and used only by each usergroup. I did this by copying the poll module and then copies the front-access module access module identified the individual module ID accordingly, then on the matrix, I ticked the boxes accordingly. When I preview it, the 3 modules are seen at the same time. What did I do wrong?

see manuel point 9:
Disable the module which is now loaded in the Frontend-User-Access module, just to make sure it does not show anywhere except within the Frontend-User-Access module.

Thanks, where can I download the manual. I've looked around the site and there are no clear sign showing documentation.

There is no manual to download yet. The manual I am refering to is in the FUA configuration, tab 'module access'. there is a link to detailed instructions.
