Most wikipedia users can move a page over a "simple" redirect, defined as one that has had only one edit. That situation is becoming rare as templates are added, double redirects are "fixed".
Steps to Reproduce:
- Wanted to move a page over a redirect but couldn't because User:AvicBot had fixed a double redirect, which brought the total number of edits on that redirect up to 2.
- Wasted everybody's time getting that fixed and went about it the wrong way, which wasted more people's time.
The discussion at Wikipedia:Village_pump_(technical) proposes changing criteria for "simple redirects".
