Often I come across comments I want to share with my partners on this site. Copying the url then creating a private message then choosing partners names can be done but it's more of a barrier than I'd like to admit. I'm not even sure I can focus the url on the specific comment.
Since we have a partners list in our profile already, why not allow an alert to be triggered by me to my partner pool? That way the communication is instantaneous and if we want to communicate by site email we can do so later as a follow up discussion.
Plus... it's free!
