May I ask why you need these two tags created?  Not every program in the repositories requires a tag, and tags should only be created  when they are **absolutely** needed.  Otherwise, if they're sparsely used, they tend to get removed or merged with other tags.

***EDIT***<br />
A google search of the site for `pyRenamer` only returns it being mentioned as a solution for mass renaming.  Same for `Krename`.  There is no need for a tag for a program that is mentioned as a solution - only for a tag in which there are at least a few questions pertaining to the need for support with a program (i.e. "pyRenamer won't run, how can I fix this?"), to which this does not apply.
