I just had my first two submissions accepted yesterday! With help from folks over on the Photography Feedback forum, my initial rejections were corrected, resubmitted, and are now part of the database.
I also received another e-mail from A.net yesterday saying that with 20 posts under my belt, the Respected Users features have been unlocked--"Use it to recognize other users that you believe deserve your respect. Other experienced users can give you similar recognition." Forgive my ignorance here, but what exactly does that mean?
