I just thought of a great idea for Kazaa users. This idea requires no additional software or tech jargon.
Simply right click on each of your downloads, click "Send Message to this user" and type in a quick Thank-You! note to each one of them.
Many will have messaging turned off, and rightly so with all the Spam, but imagine a typical users' reaction. They see your message and think it's another Spam (many start off with Thank you for sharing! and then they realize all it is, is a thank you. This will make them feel just a little better, and maybe they'll use Kazaa more if we share the love.
If you wanna be a cheap bastard (don't worry I do this too) write out your first Thank You note. Highlight the whole thing and hit Ctrl+Insert to copy it to the Clipboard. Now hit Send. Next one you open, merely hit Shift+Insert, to paste.
Let's try it. It certainly can't hurt anything.
PS - I'm not a Christian, if anyone's wondering. I'm a hippie.
