I got one of those unexplained rejections and I did email support. Have not heard anything from them, as yet.
The rejection said "Titles may not contain camera name, web address or other unnecessary info." This was a first for me. Oh, by the way, one photo was named "Pierogies for Dinner" and the other was named "Plate of Pierogies." For those who may not know, pierogies (or pirogies, depending on who is spelling it) are like ravioli...Polish pasta with potato, sour cream and chives inside). Is there a Pierogi Camera I don't know about? Unless there is, this was a bogus rejection.
I don't think taking this to the forum would do much good. Oh wait, I just did take it to a forum.
I'll go look for that thread you are talking about, JoAnn.
