How do you message?

I ahve not been able to figure out how to message users to figure out how to thank them for files. can someone please help me? Thanks

Hi suddensyl
when U right click on the user (in the download section or under Users, ....), you could call for "Message user". Once chatted it will stay there until you drop him.
Being polite is the right way :-)
