Lol, this may seem dumb, but how do you reply to answers?

[June]

you don't - this is a question/answer forum, not a chat site or a message board where you start a thread

you ask a knowledge seeking question

the Additional Details function is for adding more info about your question, not for chatting to those who have answered

you may say thank you under Asker's Rating if you pick them for best answer and you can leave a comment under the BA and each of the answers

comments must not be chat, must not ask for email addresses to be exchanged

if their email or IM is enabled you can contact them that way but they may not respond

"the same question has been asked 1000 times, just this week" @#$%! I KNOW!
