I have been upgraded for a few months now and will continue to be for a while yet. What I really appreciate is the free bonus credits, random referrals and increased downline levels, as sum up to make a worthwhile monthly upgrade.
If I was to suggest anything that would enhance my experience as a premium member it would have to be a few free banner credits each month, but I am happy as is without them :-) (Warmest Regards, Chrissy J - MFMO admin)
