@vulcanccit...yes, it may take you a few tries to get "certified" at some of these sites....usually they will tell you the reasons.  Most often the rejections are due to noise.

As for your own site....perhaps a starting point to make it more well known would be to add a link to it in your signature here and at any other sites you may frequent.

Best of Luck!

In youth, we learn....with age, we understand.
