Know that one. Mainly a DBA, SQL programmer. Have been software tester too and believe me I spent a long time wandering round, trying to work out why the basic things failed, in my eyes.
All you need to do though is to create a topic here, or on your forum and link to it both from here and the mod description download. When a certain common question ciops up a lot add it and answers.

Q: After installing the mod users not in groups cannot see groups on different permission profiles
A: This mod allows extremely specific permissions settings and so you need to be specific about what you set. Rather than Regular Users when adding which groups a board is visible to you need to add the board to all of the relevant Post Specific groups such as Newbie, Jr, Full to the permissions to the required groups. Regular Member no longer is a total catchall for anyting but the Default Group.
