Hello. I would like to build a membership directory for my members, as well as import over 1,000 members into the new XOOPS site I am building. Can I easily add new fields into the user table without messing anything up? Ideally I would like to have all my membership information in one place, as well as be able to use it when creating a membership search.

Also, is there documentation availble so I know exactly how the groups/users are tied in together?

Thanks.
