Nah..I just play with words in my head all day and night long and when one comes I check to see if it's regged and what results it has. Then I post them here. Just for fun. Funny thing is that I have lots of soso names in my own portfolio which I regged earlier on and here I am handing out some decent ones instead of regging them myself.
Well prolific does have quite a number of trademarks on it actually but I guess it being a generic word it would be fine as long as you dont use it for any of the products or market sections for which prolific trademarks already excist.
