Hi!
I am facing a similar problem. I tried to join the community in february and confirmed the CODEX TOU then. I had to wait a while a finally got an CODEX Registration e-mail saying "thank you for becoming a member of the Code Exchange platform".
Today I wanted to join the SAPlink project but was told again to confirm the CODEX TOU.
Even if I login to https://cw.sdn.sap.com/ first and then navigate to the SAPlink project (which is not as easy as it sounds) I am told to accept the CODEX TOU and then it says "You have already accepted the Code Exchange Terms of Use and your request is being processed."
I don't understand that procedure because I thought I went through it successfully in February.
Can anyone help?
