Joomla

So I integrated my site with some joomla to get some extra pages and such for all the info about local music on my site. I would like to have a link that will take to to your elgg profile after log in. any ideas here.  I tried the simpole way of copying the link location but got this

http://archaicradio.com/social/pg/profile/waylon

I am assuming that the "waylon" needs to be replaced with some sort of php thingy but it's beyond me.  is there a simple link I could put in that will redirect a logged in user to their profile?

thanks
