Either advertize blitzmax alone, or advertize your product and blitzmax at the same time, i would go for the second, if you want it then dont hope for someone else to do it for you, do it yourself, you tried the complaining and it didnt work, now try the action part and see what it does.
I'm guessing you don't have any products to advertise? If you did, you'd know that advertising is about picking the right audience. People who play games are not a worthwhile audience to advertise BlitzMax to. You might as well advertise cookery courses to people buying takeout pizza. You'd probably also be aware of the possibility of destroying sales of your own product while you failed to do anything for BlitzMax in the same breath. Bad idea all around.
