You nailed it: it's not legal advice, but you might need legal advice from those lawyers, and it's definitely helpful if Docracy helps you contact them. I don't see anything unethical in this, also considering that the service is free for all users, lawyers included.

We actually have pretty reputable contributors, like Gunderson Dettmer LLP. Lawyers who realize that lawyering skills lay beyond standard templates are also generally better (or at least more human) than those who charge you $500 for a template they've been using for years.
