We are moving our help system for Tetrad from this group to our GitHub repository issue tracker. Instructions are at the bottom of this page:
Please use this system going forward, as it will help us to keep track of issues a lot better. Also, you will get email updates when issues are worked on. Plus, you can add comments to your issue if you like. Plus, other people will be able to help you out. Plus, you can can look at the source code yourself now more easily, as it's been converted to an open source project.
