Search Submission Tool

Im putting together a free web based tool available to anyone who wants to automatically submit their website to multiple search engines at the same time. I know this has been done before, but I haven't done it and its pretty much a learning experience for me. It is currently functioning, and I will be adding some additional search engines, but I was wondering if anyone would be willing to take a look and offer any suggestions for improvement. I apoligize if this is in the incorrect forum, but im looking for as much feedback as possible. Thanks, Erich Kolb
