? Different Users / sorting / display

Hi,

I love the plugin, it’s very powerful. But I have one Problem: I’m building a site with different users, everyone has it’s own profile. How can I list of all of the Posts of any specific user?
If I use [usp_display_posts userid=”current”] the posts of the logged in user will show up (of course) but if I visit the profile of my colleague, I need to see his post. Is my question clear? Hope so… Thank you very much in Advance!!

Regards, SCPro
