Okay, I'd better clarify. My son installed PunBB on my Linux system for me. I have very little knowledge in Linux.
I take it that using a different database isn't a big deal, e.g. a name change in the setup, so I have no problem with that. The users will have the basic forum abilities, to post, avatars, smilies..., since this is not a techie type forum, there is no reason for them to have it.
The main idea is to have a forum for Anoka Sr. High and another for Blaine, Coon Rapids, and so on. This way the classmates can communicate with each other without having to pay a fee and in their local area (unlike Classmates which covers the entire country. This is why I wanted to have the ability to restrict the areas of the forum to only the graduation year (e.g. 1972) or a group of years (1970, 1971, 1972, 1973, 1975). The second set due to the fact that many classmates had friends two years ahead and two years behind them. But afterwards, having it for each school may be better, since it allows a family members to communicate for another (dad/mom is deceased or computer illiterate).
The question would be, how much access is required for a moderator? If I have one member from each class as a moderator for their group, am I having to allow access to the whole database or just a table (or two)?
