Reciprocal license- required to "hang" for access to MLS?

[Tucker Helmus]

Just a quick little background on my situation. I recently moved to Massachusetts from Colorado, where I was licensed as an associate broker (essentially the same as a real estate salesperson in MA) and I am in the process of applying for a reciprocal license. I would like to utilize the license for the sole reason of gaining access to the MLS for investment opportunities (i.e. I don't plan to be a buyers/sellers agent). So my question is:

Do I need to hang my license under an employing broker in order to gain access to MLS? Or can I simply sign up as a licensed Massachusetts individual and be off to the races?

Any input is greatly appreciated.
