I'm thinking of closing the individual categories for special projects. There would just be one top-level category called Special Projects (like there is now) and then instead of sub-categories for Mayflower, European Aristocrats, US Presidents, etc., those would be tags on http://www.wikitree.com/g2g/tags
We've been using the tag feature just for surnames. This would mean mixing surnames with other tags.
Functionally there would be an advantage. We're working on a feature that will enable you to watch a list of surnames/tags, e.g. you could get a feed of G2G Q&A tagged Smith, Jones, etc. By broadening the tags, you could watch Mayflower, US Presidents, etc. in the same feed.
Are there any functional disadvantages that I'm overlooking?
