This add-on saved my butt! I accidentally perm deleted a thread. I was able to pull it up on google cache, copy/paste the posts, then simply use this add-on to easily change author of the individual posts. Whew! - Thank you!
We have an RSS fed robot that posts news for our forums, but occasionally 'I' will post such threads when I trip across news related to our website. Then I can simply Change Author of the new thread over to our NewsBot. This add-on makes it really simple and fast to do so!
Installed and works good on XF1.5. This add-on is so handy where you want to draft posts for other members but don't want to actually log in as them (either overtly or covertly) which has privacy implications and can trip multiple account detectors.
