Oh man, this is bad news. What separated SIM from any other UML modeling tool out there was that it was both mature enough for professional use as well as free of charge, also for commercial use. Other products are not able to provide both.

Now that it's licenced, I can't use it at my work anymore. No matter how low the price tag, when you work at a company, you always have to get authorization for purchasing a license for a piece of software. And a lots of software houses (as mine) have negotiated prices for products such as IBM Rational or Visual Paradigm. So even if I would want to purchase a SIM licence, I will be forced to go with one of those heavy-weight monsters... (; I believe this is a case with lots of SIM fans.

I do, however, understand that you want to get paid for the hard work you've been doing, and I wish all the best for you and the future of SIM!

Hallo! SIM 4.0 is a great software for our company! We use this program already 7 months and I must say we were surprised that it was free of charge. If it is true that the program is being developed in your spare time, then your step fully understand. And 69€ for one license? Compared with other programs it is a good price. On Friday, the boss bought us a license to four computers. Have a lots of ideas and a stable price:))

Good news man. The only think I need to know, what is that small fee for commercial licence. Thanks.

I think adding the non-commercial payment is a mistake... I work for a small business, and was using your modeler because it was free. Now I need to go on the hunt again..... :'(
