Thread:Project:Support desk/The problem with moving pages between namespaces

We use MW 1.21.1 for an internal wiki (not accessible from here); we recently upgraded from 1.19.x

In MW 1.21.1 (but perhaps earlier), the Special:MovePage dialog changed so that the namespace is in a drop down. This continually causes trouble on our wiki. Often, folks will accidentally create pages in the main namespace when they intended to create subpages from their User:&lt;userid> page. When an editor suggests they move the page, mistakes are not uncommon. Despite having very clear help instructions for how to do move a page from the main namespace to the User: namespace, they sometimes leave off a step. Either they forget to change the namespace in the drop down, and end up renaming  some page  to  userid/some page  or they leave off their user name and end up renaming the page from  some page  to  user:some page . Worse, they also sometimes forget to uncheck the option to leave a redirect behind. Then, they discover their error and try again, leaving an even longer trail of tears (double redirects, etc.) Now, admins must be enrolled to clean up the mess by deleting these extra mistake pages (only admins can delete...)

I don't recall seeing such problems with the old UI. An editor would suggest changing the page from  some page  to  user:userid/some page  and people only had to copy/paste the name into the move/rename dialog, and there was much less chance of error.

Is there some way to reenable the older UI - an option/preference setting? Or a simple change to a .php file?
