I often move AAQ to relevant forums that are active, if they originated in AAQ and they added an email for replies, they continue getting notified. Moving them to active forums like daylilies, iris, roses, plumerias, etc. get those threads seen by members whose interest is in those related plants, thus a higher likelihood of getting more specific responses. Often I wait until there are one or two replies added before moving so that they see those responses in their email. They click on it from there and automatically get taken to that thread, no matter where it is now. They will most likely have no idea it was even moved because most start their AAQ question from an entirely different format than someone coming into any other forum and scrolling to the bottom to start a thread.
A large majority of AAQ new posters don't come back into a thread for whatever reason. Possibly they are not interested in forums with ongoing discussions, they just wanted a basic question answered and see no need to come back, even to thank members who do add their replies.
