One or two bad apples may not spoil the whole bunch but they sure do make a foul-tasting pie
I've built, from scratch, a few useful Drupal contributed modules for my own use, and shared them via the Drupal.org contributed modules system. I shared them as my way of supporting the Drupal community (since I benefited from the freely-available Drupal core and other contributed modules).
While the vast majority of users have been polite and reasonable, and a few have offered support, on the whole I find that the majority of users seeking help or reporting bugs do so without offering much in return. Most of the time it seems like a one-sided relationship.
I do appreciate the information most issue reports have to offer but I am unable to respond to all requests in a timely manner. I've been very busy with other priorities over the last year or so, so I've not had much time to dedicate to maintaining the modules I've contributed. The support requests and bug reports have been piling up. As a result I'm seeking new maintainers for all of the modules.
Further, I've decided that I will think twice before sharing future custom Drupal modules via Drupal.org's contributed modules project hosting.
