Auto-email to users following a lead/account when note is added.

Auto-email to users following a lead/account when note is added.

I am thinking of switching from Salesforce to Zoho due to the workflow automaiton features.  The one thing I do find extremely helpful in salesforce is the "chatter" function within each account/lead for discussions between users.  I noticed that zoho allows the addition of "notes" to leads/accounts which is essentially the same thing.  How do I have people who own or follow the lead/account get auto-emails when notes are added to the lead/account?
