Postcardware

Postcardware licensed software inherits all conditions from Freeware with one exception. It's still free to use for unlimited time period, but if you like it you should send me a postcard. And I'm telling here about a real postcard send via postal mail, not e-mail. This postcard should have a nice image of your city/town on one side and a few kind words of support from you on the other side (or anything else you may want to write there). If you want you can send me also something small (that will fit into the envelope with postcard) like a coin or small sum of money. But remember, that the only required 'price' is at least one, real postcard. After registration you won't receive any unlocking codes or anything like that - it's not shareware so it will never expire even without registration. By sending me a postcard - and thus registering my software - you're supporting future development. An also I can show those postcards to my friends and amaze them :).
