Hello All,

I'm working on moving from Dolphin to UNA. On the member profile pages of my Dolphin site I have set a block that displays an RSS feed of the member's (the person whose profile is being viewed) latest posts on another website. On my Dolphin site profile page, for the RSS URL I use: …./user/{NickName}/submitted/.rss as "NickName" is the parameter for the user's user name on the Dolphin profile page  and as long as my Dolphin member has the same user name on the other site that they use on my site, their latest posts from the other site automatically show on their profile page on my Dolphin site. The RSS address automatically replaces the {NickName} in the RSS URL with the username of the profile. This functionality is important for my site so I need to work it out before switching to UNA but I can't seem to find what has replaced  "NickName" on UNA. The user's full name/user name is displayed on the UNA profile page but I don't find which profile related page contains the code that will tell me which parameter to use. I tried "display_name" with no luck so while that seems to be used elsewhere it doesn't seem to be what is used on the profile page.  

Any ideas would be very much appreciated. Even if you don't know the parameter used, if someone can tell me the file(s) that create the profile page on UNA, hopefully, I can figure it out.

Thanks!
