Dear, Darling, WikiTree members,
Please, PLEASE, P-L-E-A-S-E! Stop using state abbreviations on United States profiles! I know it's tempting to do it and it's something we all do all the time in every other usage. But it really hurts on WikiTree because the "match" program doesn't pick up that "PA" is the same as "Pennsylvania." This results in hundreds (if not thousands) of duplicate profiles, which leads to merging nightmares, which leads to lots of us spending time that could likely be more wisely and usefully spent in adding sources and improving or linking profiles.
When you run across a profile with an abbreviated state, please expand it! When you're importing your GEDCOM, please change it in the profile before leaving!
Maybe this could be added to the Newbee instructions and helpful hints pages?
