Re: Problem with LEF OUTER JOIN

Indexing the tblthreadreplies.ThreadID and the tblthreadvisitsbyuser.Thread fields will speed up your query immensely since you have specified a single thread to be search for. Right now it has to conduct full scans of each table. With no indexes whatsoever the optimizer has nothing to work with to speed up the process.
