First I'll post the old list from the DAZ forum archives.  I pruned one name (Patrick Stewart) because there was no link associated in the original.  I have not validated any of these links or their associated products so YMMV.  I have cleaned up the code a bit but my HTML is rusty (and was never that great to begin with); I've done the best I could to work with the crappy forum code (it likes to add and remove code at its own whim):
