Maybe not with html but you can submit a form and do a redirect at the same time in javascript. I just really suck at it and don't know the exact code but I've used it before a couple of years ago in a forumblock of my own. If I had the backups to that forum I'd be able to post what worked, but alas they're long gone :(

It's possible if the form is being submitted using AJAX indeed. Going to be rather tricky in an onclick though.

I appreciate the input atleast I have a direction to work with. I will look at the hook and the js options. In the mean time just gonna hide the block after they click it and have another block with the link to the roster appear. Thanks for all the useful info.
