Often I can't remember my two User-Id (or IBM-ID) and it confusing too.
Sometimes I have to provide a User-ID and sometimes I have to provide my IBM-ID for logging into ibm.com ...
Just add support for OpenID for all services at ibm.com! I do not like to have two "user accounts" at ibm.com and ibm.com/developerworks/ ^^
I am wondering that there is no ibm.com ida space ...?
