I agree. If no one has already done this, I will look at modifying the plugin.
Apologies, this is the first time posting on these forums. This is concerning the allow_numeric_stubs plugin. The plugin page linked me here so I assumed it was going to a plugin specific forum.
Also, with the plugin activated I did some other testing. Using the default permalink worked as well as using /%year%/%postname%/ and /%year%/%month%/%postname%/. However /%category%/%postname%/ and /%postname%/ did not work. I also tried hard coding the category, i.e. /events/%postname%/. That did not work either.
