I want to post a bunch of urls that look like this:

http://somesite.com&SID=_____

The blank is the users id from my site. For example bobby is user 8 on my site (looking at the uid on xoops_users table). When he looks at this page he sees a bunch of links and when he clicks on them they go to:

http://somesite.com&SID=8

This is so I can track who goes to the sites and completes an offer (I'm an affiliate) at those sites. Does that make sense?

I figured out how to call up their id right at the registration page but I'd like to be able to after that. Someone help!

Can you clearify a little more on what it is you would like to do? What is the exact proces you would like to monitor?

I really don't need to monitor at all.

ALL I need is for the ___ at the end of the link to be filled in with the users id.

I think I explained that well enough. that's ALL I need.
