If so, you need SAP Universal ID. In a few months, SAP Universal ID will be the only option to login to SAP Community. Without it, you will lose your content and badges. If you have multiple accounts, use the Consolidation Tool to merge your content.
Can someone please direct me to where I can find a full list of all document types and their description. I believe I found a partial list here, but wasn't sure if this was everything.
