*** As of patch 5.1, the free company is open for applications again, so please see the above threads on finding us. ***
Our guild leaders are going to start pruning members more aggressively than they have been, which is going to free up a lot of space in controlled chunks as people move in and out of the game in-between content-lulls.
From our announcement channel:
"On the subject of the FC cap, we will be removing inactive members after a while in order to get some newer and more active people in the FC. We don't have a "Days last online" limit or specific day we will be pruning the FC list, but it may happen from time to time. If you happen to get caught in that wave, don't take offense. We just want to get some other Duders who are playing the game more frequently a chance to play with the FC (the LS will still be around, so this is another reminder to join that if you feel you aren't going to be on as others)."
