When I make freewares, I make them free. I don't force the user to enter his/her personal details OR pay $5 to use them. That is an abuse of the word. Call it either shareware or demo, but not freeware.
As for insulting your users, that is going to earn you a lot of good karma. If your program works like crap on my configuration -as I described-, I have the right to say so.

And for the "just curious but what did you EXPECT it to do ?!?" well, it can do as much as it likes, by previewing what it would do before doing it, and as long as I can *UNDO* it. But of course you'd need to be an experienced mac programmer to know that, instead of someone gathering a spam list.

You know, you'd have a LOT more slack if you had made it a true freeware - or shareware, as long as you CALL it so -.
