Theme My Login: redirect edit

I just had a question. I know Theme My Login is set up to allow filters for certain things (I’ve already used such filters like tml_title_filters with great success), but I need to sort one out for a custom redirect.

I, of course, have the redirects set up on the site, no problem. I want to redirect the end user – once they log in – to their profile. However, I’m trying to keep them out of the back end, and I have a custom function written so when the end user clicks the “View Profile” link I have set up, it takes them to a profile front-end Page. The profile they see is edited by adding in “?username” at the end of the URL.

I can’t really do this type of redirect with the plugin, so I was hoping to use a filter that would allow me to redirect the end user to this page: http://whatever.com/profile?username. So far, all I can do is redirect them to http://whatever.com/profile – which doesn’t retrieve the proper information.

Can you help me sort out what filter call I need to make? I was thinking it was tml_request(), but that’s apparently for actions. I can’t seem to find the filter I need to pull this off.

Thanks!
