I was working on moving a regular pt site to wordpress plugin where I implemented one extra field under Optional Index Fields.
I started with creating the one extra index field but then I saw you created a modified includes/admin.php, admin/feeds_register_step2.php and admin/database_tool.php for me (http://www.pricetapestry.com/node/4388).
The files seems to have changed a bit with the new version and also the sleep mod isn't in them.
Would you mind looking into the files what to change? Could I send you the two sets of files?
