I'm a librarian who uses Yahoo Pipes in combination with RSS feeds for new books from Amazon to order books. The title tags in each individual item begin as in this example: "#1: A. Lincoln: A Biography". I would like to add a regex expression that will strip out the ranking (#1: or #10:) out of the title so that I can sort the book titles. What I want to remove is the # sign, the ranking number (one or two digit number), and the colon. Any help would be appreciated.

Probably easy question about PHP and unicode (UTF-8) and RegEx. I'm trying to modify a php webcalendar (VTcalendar) to allow Japanese text in calendar postings. I've found all the variables to get the UTF-8 headers, and so japanese text manually inserted into pages appears fine. But, there's an input validation thingy I don't know how to modify.

Also, I’m also seeking to block all incoming requests for one particular URL which is popular with these video and image search engines but which no longer exists – but I don’t want to serve them the normal 404.
