2) I need a hack/script that deletes users that have not posted yet but have been registered for more than 2 weeks.....Is this possible?

For #2...

Go into the admin CP.
Click on "Users" in the left menu.
Click on "Prune/Move Users"
On the right, usergroup select "registered"
Has not logged in for x days - leave blank
Join Date is Before - put in date that is two weeks prior to current day
Fill in the field that says "Posts are less than" -- put 1 in that field.

Click on "Find"

This should bring up a list of users who have been registered 2 weeks or longer but who have never posted. You can select to delete them or move them to another group. (click on the checkboxes next to the people you want to delete or move to another group, then scroll down to the bottom and select what you want to do).

Hope that helps!
