We have no plans of ever moving away from our email system and putting it within opengoo. It's not that we dont trust it, it's just that we have our system setup in a very specific way and it works excellent for us. Moving it to Goo would not make sense.
Now, that being said, with some other systems we have enjoyed the ability to compose a email and send it to our task manager and it converts it into a task.
So, if the admin needs me to do something, he sends a email to a specific email address, and it pops up as a properly formatted task within Goo. This works great for the people who like to task out jobs in the bathroom with their phone, or on the road.
That's just something we would like to see someday.
