No. If I understood Anna well she is saying none of the usernames were considered as valid by Wikimetrics.
I have problems too. Inmediately after I register appears a rose box with red writting that ways "Error! Wikimetrics is experiencing problems. Visit the Support page for help if this persists. You can also check the console for details."
I can't see my old cohorts. Although I can see the menu to create new cohorts and I can introduce info, but when I push the blue button to create my cohort I don't get any result and everything desapears. I attach a screenshot of the result.
Thoughts?
Regards!
