A few random points:
-There's no way to delete pictures you've posted on the website. You can only swap them out for other pictures.
-I think it would be better to give multiple potential matches at a time as opposed to just one single one at a time. Saying no to one and then waiting 2-3 weeks for the next match is too time consuming. 
-Match makers should respond within X hours to text messages/emails. There should be a set time limit.
-Weekly checkins via text/email are great.
-Not sure if there were a lack of people but I feel like my matchmaker didn't have enough candidates for me, which is fine. But I think honesty is the best policy in this case.
