I'm finding myself pretty much in agreement with gee here. The removal of author pages that don't meet the criteria seems totally fair to me, especially given a monthlong grace period. If tech can come up with a timer like they did for deletions, then that would make things even better, but honestly this happens so rarely that it might not even call for that level of attention. Might as well do it regularly or something, maybe pawn it off to MAST for an annual "spring cleaning".
However, I'm not in favor of doing anything to the current author page system for the same reason that I disagreed with allowing authors to move between SCP slots: unless I am severely mistaken here, moving every author page to the "author:" category will break links that are outside of staff's ability to repair.
Think about what this will do. Moving every single author page will break every link in an info module, every link in an author post, every link in a reddit post, every link in a wikidot bio, every link in the description of a YouTube video, and so on. Some of these things, namely the links in articles and comments, can be fixed by tech staff if they so choose to, but the links on other platforms are completely out of our control.
It almost seems irresponsible of us to irreparably break this much functionality to fix a problem that literally affects two pages on our wiki: Crocket's Author Page and scpcrnp's Author Page.
