my real account name is "Cmdr J.R.Ehman" and I have forgotten my password.
This is me and my group:
http://boincstats.com/en/stats/-1/user/detail/3427044/projectList
http://boincstats.com/en/stats/-1/team/detail/155476707

Unfortunately, when I use your site's account recovery
https://boincstats.com/en/bam/accountRecovery
it says that my account cannot be found. I have also tried entering all email addresses I might have used to sign up and it still says "account not found".

Can you help me?

Are you sure you had a BOINCstats forum account or BOINC Account Manager account? Every BOINC user will be listed in the stats here, but you won't have login credentials unless you created an account here to use the other features.
