Receiving notifications when user edits a node? Newbie here!
I'm running a site on Drupal 7 (iloveqatar.net) and users have the ability to submit their own content (News, Events, etc...).

I'm facing a couple of issues.

1) When users submit new content that's in moderation to be approved, I don't get any notification. What's the best module to a) send emails to moderators / admins so they're aware there is content that needs to be approved and b) Display the notification on the site (like an unread message counter).

Right now I click on "Needs Review" on the admin bar on the top of the site every few hours just in case theres new content.

2) This one is the more problematic issue. When a user submits an event for example, and it's then approved, the user still has the ability to edit his/her post, which then creates a draft that needs to moderated and approved. However since it's creating a draft of an existing note, I'm not seeing it under the 'needs review' table. I actually have to go to that specific event and then edit it to approve the changes. Of course that's no good for me, because I can't go around checking every single post just in case there's an edit.

Does anyone know of a solution for this so that I can get notified and/or it shows up in 'needs review' ?

Please do let me know if I need to include any additional information to get help.

Thank you so much in advance!
Newer versions of the Workbench Moderation module integrate with Rules.  I am not sure if the patch is in the stable tree, or whether you need to use the dev version, though.

Assuming you have a version that supports this, then 


add a new rule
for the reaction, choose Node: After moderation transtion
for the action, choose Send mail
if needed, you can add conditions based on the old and/or new moderation state.


After that, just configure the conditions and the email that gets sent out.
