I have yet to login to the official site to formalise my participation. But I won’t do that till much later. Don’t need the community pressure.
Yes, the community is great, it’s encouraging, and welcoming and motivating. On the flip side: Everyone is pushing for 50,000 and word counts are posted with nano-second frequency (pun intended). For me, that is neither pressure nor energy that I can deal with right now. And logging in transmits that stress and hyperactivity. On the other hand, participation away from that intensity is much more conducive to writing.
