as somebody else noted why not put it on some sleek way where your consumer dont get irritated and you can clearly show your message.
Well the world heading the way it is now every-thing's price climbing mountain and the economy I think it will be little help for all the developers who devote all that time and there skills to keep community happy and growing would consider some kind of monetary thank you or a donation or some sort which will keep them going.
P.S. I am not a developer just a consumer.
Not into learning either, too lazy to learn all the coding.
