I received a couple of calls complaining that ads placed under the Aircraft for Sale section was being deleted.
The system was set to auto-prune posts and delete them after no activity for 61 days. I have increased this to 120 days and will see how it goes.
I courteously request that if you want your advert to remain "alive" that you "bump" the post say once a week to keep it active an on the first page....

Hope this helps
