Registration is free and easy.
Registered visitors will be able to run premium simulations that are more sophisticated than the basic simulations available to unregistered guest users.
Visitors who register as authenticated users can also post comments on articles, view other user profiles, contact other users, and start forum threads.
If you choose not to register, you can still run some of the basic simulations and read the general information on the website.
Please note that the email addresses of everyone who registers are NOT viewable by guests or other users, and we at SimSmoke.Org will never reveal them to anyone.
