I have a listing of department alumni which calls up their email address when one of the form buttons (letters of the alphabet) is clicked. The emails are not hard-coded; the form sends the $letter to a php script which handles all the usual stuff (the query, getting the array for the query, printing/formatting it). Is this type of thing accessible to spiders? They can't actually perform actions on the pages can they? Sorry if this is a stupid question, I've been reading along with this discussion. From reading what's been said so far, I'm guessing the only email they can get to is the webmaster address on the front page of the site....
