Reading and commenting
Many of my friends want to read and comment, but they don't want to open an account here. I wonder if it's possible.
That would open a big can of worms. Spam, abuse & anonymous multi commenting would be rife. We did have a comments system that was using 'Disqus' as it's backend so anyone with a Disqus account could comment, but no-one seemed to like that idea (having TWO accounts to be able to comment - UKA account + Disqus), so we got rid.
