I don't think hyperdictionary.com has been mentioned here, but, anyway, it's kinda neat. You submit a word and it looks it up in whatever combination of the following it finds appropriate:
English Dictionary
Computer Dictionary
Thesaurus
Dream Dictionary
Medical Dictionary
For example, if you enter "incest", it gives you definitions from two dictionaries, one of which is the 1913 Webster's ; thesaurus terms; and a discussion of possible ways to interpret a dream about incest. (For example, it may "be representative of the union between masculine and feminine aspects of yourself".)
They provide the necessary HTML and Javascript code to put a submission form at your own Web site. I've done that at the aue related home page (
http://tinyurl.com/yltj ) at my Web site. I've also installed a file at my Web site that has the submission form only (
http://tinyurl.com/ylv7 ). If any webmaster wants to incorporate the submission form at their Web site, they could lift the necessary code from the latter file. But they should still read what the
hyperdictionary people say about the form at their Web site (

At the last-mentioned link they tell you about adding the form to your own page and supposedly provide the code to do so. It turns out, though, that unless I've overlooked something you need a little more than what they say you need. I've lifted the necessary additional code from their page and have incorporated it in the two places I've mentioned above.
