Drupal 7 Limit Published Nodes Per-User

Question

So I have a pretty specific situation where I have users who have X (unlimited) nodes authored by them... yet they are only allowed to have 6 nodes Published at a time.

I googled around for a while and found http://www.badzilla.co.uk/Drupal-7--Node-Limit-Publish-Module , which works GREAT, except this limits the TOTAL number of published nodes of a particular content type.

I need this exact functionality, except w/the additional limitation on a per-user basis... So that each user can only have 6 total nodes Published at once, rather than the entire Drupal Site only having X total of a particular content type published at once.

Hopefully that makes sense... regardless, the code/module from the URL above is exactly working great, just I need to cater it to check on a per-user basis! I'm not great with module coding or anything, so if someone is able to handhold a little on how to alter the module code on that site, that'd be great! TIA

my first instinct is make a rule that checks on publish that checks how many nodes have that user as author...pretty new to drupal, though — Ken

For anyone who runs across my same issue, of needing to limit number of PUBLISHED nodes of a particular content type, a friend of mine altered the above linked Badzilla module, and tweaked it to be the following. Thanks to Badzilla for providing the basis of the module, and my buddy for tweaking it to check on a user-basis rather than site-wide # of published nodes.
