When you have entered into a conversation with a person who asked a question, are you allowed to exchange email addresses or phone numbers? I apologize I did not know exactly how to tag this. I'm learning how to use this site I like it very much and want to be able to follow everyone's guidelines and policies.
Only in comments, and since you don't have enough reputation on any site to post comments to other members, the really short answer is no.
We prefer that you didn't. There are a number of reasons why.
Users who want to reveal their email addresses or phone numbers will usually put them in their profile, so you will find that information there, if it is available.
In general, we're not a clearinghouse for contact information, nor is our purpose to facilitate communication through other means. We are a question and answer site, and we prefer to maintain that function exclusively.
