I would like to suggest that wordpress create a built in function to automaticly post the TITLE and URL or evaryone's posts to OpenSubmit.net.
I run the servers for opensubmit and I think that It would be a great way for people to get their sites listed.
I am suggesting that as a builtin function as apposed to a plugin because this is something that all blog users should have access too. Please contact me at [g e x at m a r d o x dot com] if anyone wants access information for OpenSubmit.net. I am willing to provide an exclusive PHP script for this project.
But in theory this is how I see the function working. two feilds. the wordpress software would post to the following URL when the user posts a new blog entry.
This is just an sample URL
my script will take those two feilds and index them into the database.
Please let me know.
