After months of work HCL activated the community forum for HCL Notes & Domino today. You can register for free though your HCL FlexNet or Support and Partner login also may work. I preferred a personal login to post there with my own name.
Please allow up to 2-5 minutes for the confirmation mail to appear in your inbox. Also check your SPAM folder as mails from HCL may not be on your whitelist, yet.

The first thing I noticed is that HCL did not choose Domino as the platform for it - which is obvious as the forum also contains the other brands and topics and not just Notes & Domino. My first impression is that it's very fast and decent.
See you there!
