I just wanted to ask, why there does not exist any personal messaging system in this site, just to be able to contact users? At least, moderators should have this ability to contact users personally in case they want to note them something.
As an instance, somebody wanted to inform me that it is better to change my way I am doing tag edits. Because moderators can not send personal messages to the users, he/she had to comment under one of my questions. His attitude to help me to learn something about tag edits was great (I am so thankful to this attitude), but the way he informed me, brought my energy and courage to participate in the site, down.
