First off, I have to say that the new 'bulk edit' and 'bulk delete' features are excellent and I'm sure will be a huge time saver for developers and end users alike!
 
However, what I'd like to know is how to 'trigger' the acknowledgement emails from the grid, after a bulk update.
 
At the moment, my individual records fire off an acknowledgement email from the details page when they've been updated. After updating them in bulk (or using the grid edit), I lose the acknowledgement email functionality unless I open the individual record and manually click on 'update' on the details page.
 
Can the update button that triggers the email be included on the grid?
 
Any thoughts would be appreciated!

I'm looking to create a rating option which uses a star system, like Amazon feedback ratings etc.  Is there a way to do this from within a datapage.
 
Also, is it possible to use the rating selected in a calculated field?
 
For example, if 10 people awarded an item 4 stars out of 5 and 10 people awarded the same item 3 stars, can we show that the item scored 70%.
