According to KB0035276 (you have to be logged into Epicare to view)
Marketing, support, and development staff throughout the year review enhancement requests. If enough customers request a particular change and it is in the best interest of a majority of users, it may be added to the standard system. Support is a way for you to communicate new enhancement requests and will submit them on your behalf, but plays no role in the enhancement approval process. The more customers who have called in or requested an enhancement request, the better it’s chance to be added to the standard system, but it still would need to be reviewed by the aforementioned group.
What do you guys think of a monthly/weekly poll to vote on existing Enhancement Requests and then everyone calls in to request it? This site is now up to 2970 users and that might make a difference.
