This is a great site for info. No question. Don't mind those that may not appreciate your situation as there are many more who will gladly help you with any question you may have. As Doolittle said, name calling is a no no here so just ignore those that you feel aren't worthy of a response.

PS. We love pictures here and the more posts you read, the sooner you'll see how strange these little guys can behave. Ha..
