Yes, I know, this might sound silly, but read through before you comment. I'm looking for a "member directory" or "member database" plugin for Geeklog. This would be a normal database (MySQL for instance) with a web interface, like you can create with DaDaBIK for example. The reason for this is that I want the database I create (which will hold the details of all the members) to be separate from the Geeklog database. But - I want the access to that database to be controlled by the Geeklog access system. Does anybody know of such a beast? Or do you have any ideas on how I could solve this?

This sounds like the Contact Plugin. You could also use the External Pages Plugin and wrap DaDaBIK.

You are right, it sounds like the Contact plugin. I'll have a look at that. Thanks! :-)
