The Open Source aspect of the engine is great, but I think that engaging more with the Unreal community through the forums would be a wonderful way to fully embrace this philosophy and expand your user base. Listen, share and communicate more. We all benefit from this approach ultimately. The current one-way communication approach is intimidating and not really inviting for new users and even for people like me, that are extremely familiar with the engine. Some thoughts, for your consideration.
Thanks.
