Don't know if this is the right place where to post this question but I'll try. I tried to access the tutorial for the upcoming summerschool at https://etk.cct.lsu.edu. However, when I try to click on CILogon I am redirected to a page where I have to sign in my Github account. However, having been registered to the tutorial through my university account ac4870@rit.edu when I try to login through my Github account I get this error message. 403: Forbidden. Alessandro is not authorized. New gmail accounts are not currently being accepted. Please use your university account or Github. How can I solve this issue? Can this be related to the fact that I had previously created a github account to access the Tutorial For New Users on the Einstein relativistic toolkit website?
