Goal is to link opportunities with a Contact.  Opportunity is associated with 1 Contact, but for different locations. 1 Contact who is associated with the 'parent' account, but opportunities are associated with their other locations.

I need help with setting up a workflow please...

The workflow should be tied to a rule with a time-dependent action; I would like the rule to send an email to the Account owner after 30 days if there hasn't been activity on the account or opportunity.  I've created the field Last Updated Date on Account.

I need help creating an alert to an account/opportunity so the owner of the account or opportunity receives an alert if they haven't touched the account (phone or email) in 30 days.
