Our fourth-annual MSPmentor 250 survey ends today (June 24, 2011). We use the survey to pinpoint the world's top managed services experts, entrepreneurs and executives. The MSPmentor 250 typically includes experts in business leadership, sales, marketing, community development, coaching and more. Feel free to submit your nomination here. No need to stuff the ballot box -- one submission per nominee is absolutely fine. We'll unveil the fourth-annual MSPmentor 250 results in August 2011. The resulting list and report is a great asset for anyone looking to rapidly build a managed services Rolodex.
