Hi there

I run two membership systems on my site and I want to combine them. The first is UBB which I like for its topic posting and instant messaging. The other is a custom system that I have had built for people to register and use functionality across my site - which I like because it was custom built to my needs.

what I need now is advice on the best way to unify them. Can I allow people to register on my own system and also add that data to the Threads database... or the other way round. It's pretty similar stuff but I really needed my second registration for some of the custom stuff.

Here's my registration: http://www.teentoday.co.uk/profile/index.php?sec=register

Your best bet is having your member system read from the threads database. There is a membership integration hack at UBBDev if you want to take a look; it'll allow you to hijack the member routines from the ubb and use it elsewhere on your site.

I choose UBB over your custom solution because the UBB can and will change upgrade to upgrade, having to re-update your hack each time to do something with a new feature that isn't setup will have to require re-coding on your part.
