This limit is really confusing. There’s an interesting discussion going on in Using OneName/Namecoin blockchain as global nickname registry
@Jeremy and I asked @ryanshea some additional questions but he ran into this 3 post per thread limit after he had written up a long reply. He emailed reply to me, so now i have the answers, but no one else does.
I guess this is ultimately my fault because I forgot (until I started this post) that Discourse has an invite system that avoids this and instead just sent him a link to the topic. But it’s still annoying.
