Login problems

I am having problems to login from the page below:

https://www.w3.org/community/music-notation/ <https://www.w3.org/community/music-notation/>

If I click the “Join this Group” button, I can’t either login or open a new account, because if I try to login it tells me that my email address is not in your database, if instead I try to open a new account it tells me that my email address has ben already used! How to overcome that?

I look forward to hearing from you.

Thank you.

Best regards,
