<p>SE creates Q&amp;A threads that are focused, undergo constant improvement, display evaluation by a qualified community, and permanently exist as references and search targets.  Ephemeral exchanges, highly localized discussions, and (undocumented, unwitnessed) offline dialog work against that effort and are therefore actively discouraged and--when they do occur--are quickly removed by the community.  Therefore efforts to engage in offline contact within the Q&amp;A threads (including comments) are not supported and not appreciated when they do occur.</p>

<p>Nevertheless it's easy to contact people you meet here: check out their user profile.  If they want to be reached, they will include enough information to let you do that.  Another option is to use the chat facility.</p>
