If you find Logisim useful, please let me know! Especially do this if you use Logisim in a class you teach! E-mail me at the address given below.
Bug reports, feature requests, and questions are most welcome at Logisim's page at SourceForge.net. If this doesn't work for you for some reason, then you can e-mail me; be sure to include a truly descriptive subject line so that your message doesn't get lost among all the junk mail.
Affirmative comments will help me get support to develop the program further, and helpful comments will point out what is most important for future versions. I value all e-mails received about Logisim, as I want it to become as useful an educational tool as possible.
