Hi Hayley,
I'm working at SAP as a Product Support Engineer
I can confirm that we have a large number of collegaues using SCN, to communicate with others, to resolve questions, to share knowledge etc.
Of course we have other platforms, but SCN is a very important, active forum, and the coverage is really wide. You can find many experts here, some of them are from SAP, maybe from product support, development support or other business lines.
Best regards,
Yang
