I prefer #31 over #32 because it needs to include the "MSPintegrations.com" tagline. The round object surrounding the "M" is too busy, though. I wish there were fewer components to the round object, and that it was bolder.
#30: I don't like that the mark is a simply "M". It needs to be more unique, and a simple letter isn't unique enough.
Αppreciate the feedback and encouragement rezitech! The#32 entry was for you to see that it can be used as a stand alone mark. Will work on revisions and upload asap, be expecting to see more entries from me!
