Code to do a WordPress query for posts that start with a given letter. Assumes a letter has been passed in the URL as "?s=a" where a is the letter. This code is part of some code that handles ajax requests. You'll need to write mytheme_ajax_list() to run a proper query and/or return results somehow.
