what is your way of knowing when a question has been edited or information added to it?

Sorry but the only way to know is to go back and look at the question. That's why so many times someone has made a comment about my answer and I didn't know because I never went back and looked :(

That is a downside to Y!A. I just try to remember that it's a free service so I shouldn't be too picky about how it's constructed. The one question - one answer format is kind of frustrating 'though. That's why I find myself going back and editing an answer or question to give some feedback.

As stated by others, the only way to check is to go back to your profile, choose recent questions that you were involved with and look for a reply. Personally, I'd rather somebody send me an email than a reply on the thread.

I go back and check some of the questions I answered. That's the only way to know if someone added anything.

Unfortunately

you have to go back and check every question

btw

ppl go back and reply not only in this section

You have to go back and visit the question. That is easy to do if you click on your avatar... all the questions that you answered will pop up.

i go back and check .

btw : i do that several times :) maybe some ppl hate long replys i posted :S

my pieve is when someone picks a good answer, then in their comments, asks a question, but when its resolved, you cant go back and edit it..
