I would be interested in suggesting a new sub-category. I would be suggesting 5-10 different sites (one of which is mine).
I see that the category within which the new sub-category would fit has not been edited for some time.
The DMOZ editor profile page provides contact email addresses. Is it appropriate to notify the editor(s) of a category that a sub-category and X number of sites have been suggested, especially where no editing appears to have been done for a number of months?
Also, can you clarify if the edit date which appears on a DMOZ category is the date of last editing work (e.g. sites reviewed but possibly none added), or the date of last additions/changes?
