It would be nice if synonym words can be added down the road to common category words. ie. I use the word entrepreneurship but not entrepreneur. I can add them manually but hopefully there is a way to automate adding all the possible synonyms down the road (since people may use one or both or other synonyms). Right now I have ‘Entrepreneurship’ and ‘Startups’ as the common categories. Of course some people may spell ‘Startup’ ‘Start-up’ too. Just a feature to consider moving forward. Thanks.

This was fixed.  There's now a synonym Google Docs file at URL[LINK|https://docs.google.com/spreadsheet/ccc?key=0AsUaQihpzloZdERRWXg5QVZwYUVkbV91UTdmcTRuQ2c#gid=0]
When you build the search index, it will incorporate any synonyms to categories you have created.
