How are new tags decided? Is this done if there are say 50 or so questions containing a particular topic? I obviously don't have the reputation to create new tags, but being a regular user of Notepad++/NppExec I'd like to see a separate tag [tag:NppExec] to go with [tag:Notepad++]. The current questions related to NppExec don't have suitable tags and it makes it difficult to track specific NppExec questions marked with a [tag:Notepad++] tag. 

The [tag:NppExec] tag has already been created on SO. Would it be possible to have it on Super User too?
