Grouper will eventually mark you automatically LFG your current zone/zone's instances etc based on some profiles and such... that part is 90% done. Please browse the priority system and note any settings which don't match up to your browser (currently ST/UBRS/LBRS missing).
What is complete so far is a LFG browsing system (via fubar). Select "Scan" then click the fubar plugin until it stops flashing and says you can stop clicking.
Output is something like "LFG:DND (0/0/33)" - this basically means that there are 33 people in the LFG system that you could group with! Check the contents of the "Browse LFG" menu to look at the cached results (and to update them). "Scan" will do a complete rescan and update the user count.
