Great start - my warning - keep a 'comments must be approved' on your word press or do some research on how to stop the spamming - I have had heaps of spam comments and haven't quite figured out how to stop them all but requiring approval has only had ne get 3 submissions from spammers in about 6 weeks - better than them having open slather.
Better yet - if you want to keep it in the family and freinds make it that you approve new users...(Can we do that??? - haven;t tried but probably can) and stop anonymous from posting anything. The spammers will get you if they can.
