So fast answer, useful but not pretty extended

Hi cimiyata, I'm sorry you were not pleased with my list of sites. In
your question however, you asked for "a" website, which means "One"
website. I supplied you with 9 sites! You only needed to ask for an
Answer Clarification, as I asked you do, and I would have been happy
to see if I could have found more sites for you. For the price you
set, the answer far exceeds expected results.
