I indeed wasn't aware of that, did look into it... created a wiki page but by the time it was ready to save, I got logged out again... I'm working on it.

Created a page here:
https://wiki.openstreetmap.org/wiki/Mechanical_Edits/european_city_websites

... and will not have the script run automatically until (1) someone looked into it... and (2) I successfully updated 1 or 2 cities in a step by step mode running the script.
