I recently saw a question with both the migration tag and the sharepoint-migration tag.
- migration has 16 watchers and 840 questions, and a description
- sharepoint-migration has 0 watches and only 67 questions, and no description.
Given that this entire Stack is about SharePoint, specifying "SharePoint" in the tag for a generic term seems unnecessary, and I recommend a mod merge or synonymize sharepoint-migration into the much larger, better described and watched tag migration, since they presumably cover the same thing.
