My client list is 5,000 and growing daily. I need a program that can withstand 20X that without being bogged down or malfunctioning. My business supplys people with emails to and from social networking sites that would otherwise be unable to receive them. My company is the middle man between the two. This program should also be able to keep my clients from contacting one another on the same social networking sites through some kind of identification. This program should also be able to send my clients requested information from certain educational websites.
