Hey Alok,
We are making big strides for the future of community and having a section for promotions is being considered. There just needs to be an appropriate place for customers to promote webinars and events that could help our customers become better marketers. We currently don't have that capability so we generally discourage promotions as they can clutter discussions.
If you have questions let me know, I'd be happy to chat.
Best,
Liz
