Note:
The version number of Piaware in above thread is 3.5, which is outdated. The current version is 3.5.3. Similarly the Planefjnder feeder version is 3.7.20, while current version is 4.1.1. I cannot update it as the new format of forum (Discourse) blocks editing of posts older than a month or so.
