PLEASE READ ME!
We have created a Unified Login System for the Slitherine & Matrix Games websites and forums so you do not have remember a separate password for each of them.
If you are an existing user, you can login to the Unified Login system using any of your credentials. Then you can merge the accounts together to create one unified login.
If you have any problems logging in please do not hesitate to contact us at firstname.lastname@example.org
