Yes. Typically, the Ethical Collaboration Community Agreement is used for informal mentorship or advising, and it was designed with that in mind.
As a community, we want people to seek help wherever they can find it, and we want to encourage that dialog wherever we can.
If you are an entrepreneur who has already signed the Ethical Collaboration Community Agreement, you can send a potential advisor or mentor to http://ethicalcollaboration.org/ethical-collaboration-community-agreement/ and they can quickly sign up.
As you and your advisor develop a strong relationship, you may want to formalize that relationship with a more appropriate agreement. For example, advisors or mentors may commit to being available for a certain number of hours in exchange for stock in a company or as part of an advisory board. As your relationship becomes more indepth and involved, you may consider an additional agreement.
