Is it possible to add comments to answers like stackoverflow? And can I edit my answer after posting it?
EDIT: Commenting is now enabled by default. See para.new_users_can_comment setting.
Yes, you should be able to comment on answers and edit your own questions/answers.
it would be nice to allow that 100+ thing to be configurable. It looks to me that changing it requires a source-code change, and a recompile.
testing my responses..
This is a test response.
Correction: only people with 100+ reputation can comment on posts.
