My modification (at least since 2012) was to move "Getinvolved/Quality/Tutorial" to "Get Involved/Quality/Tutorial".
I made kde.org/getinvolved in 2005 which got moved into community.kde.org, someone else may have copy pasted something from Quality which got in here. But I don't think I have done the thing you are saying.
Either way, I'll be happy to help with the resolution. Here are the list of Get Involved/Quality files: https://community.kde.org/index.php?title=Special%3APrefixIndex&prefix=Get+Involved%2FQuality&namespace=0
Would you like to move the in-appropriately named tutorial part to the main https://community.kde.org/Get_Involved/Quality or should we put it somewhere else?
