It took way too long to do this!!! Now we share the same login for website and forum.
It might be the safest to first login to our web site if you are not already. https://trainerday.com/login Then it should be 1-click to login to our forum. Meaning you will be logged in automatically.
If your username or possibly email (not sure which) matches it should merge your two accounts, meaning you should still be the same user you were before.
