Thanks and best regards, Ralf Stephan
I think that pubpeer might require an email address from a .edu domain to make a new account. However, I have an account that I switched to my @igdore.org address, so it is possible to have this as an email address. I would suggest getting in contact with them, it seems like they are fairly flexible about making accounts manually.
No problem. Just contact us directly (email@example.com). In most cases we will be happy to create an account for you manually.
