feature request: posting anonymously...

u/lionleaf

Why not just create a pseudonym to post with? Or do you mean to make it quicker for new people to post something? I'm afraid it would just get filled with spambots
u/SpecialAgent

nice car chase. registration keeps the quality of dwits decent, imho.
u/kchplr

I was thinking about posting anonymously once you're registred, but it was mostly a joke given I'm not so glad with the outcome of this one. :D..
