Customer Support Portal
That's a special place for customers to request help to the Justinmind Support Team. Once you buy a license you receive the registration details to log in into that portal. There you can either report issues about Justinmind's products or ask how to simulate something that you are not able to do. Click this link or copy and paste this url http://support.justinmind.com to your internet browser to enter in the Justinmind Support Portal.
Community-powered Support
You might have a question or an issue that other users had too. Check our community-powered support portal (http://www.justinmind.com/community) and add questions, report problems or praise how good it is to prototype with Justinmind. People from Justinmind check this portal from time to time and have already answered many questions. If you are a customer we highly encourage you to use the Customer Support Portal instead.
