Hi @morrme

Before we can merge this pull request, we need you or your organization to agree to one of our contributor agreements. One of the big concerns for people using and developing open source software is that someone who contributed to the code might claim the code infringes on their copyright or patent. To guard against this, we ask all our contributors to sign a Contributor License Agreement. This gives us the right to use the code contributed and any patents the contribution relies on. It also gives us and our users comfort that they won't be sued for using open source software. We know it's a hassle, but it makes the project more reliable in the long run. Thank you for your understanding and your contribution!

If you are contributing on behalf of yourself (and not on behalf of your employer or another organization you are part of) then you should:

1. Go to: https://www.bigchaindb.com/cla/
2. Read the Individual Contributor Agreement
3. Fill in the form "For Individuals"
4. Check the box to agree
5. Click the SEND button

If you're contributing as an employee, and/or you want all employees of your employing organization to be covered by our contributor agreement, then someone in your organization with the authority to enter agreements on behalf of all employees must do the following:

1. Go to: https://www.bigchaindb.com/cla/
2. Read the Entity Contributor Agreement
3. Fill in the form "For Organizations”
4. Check the box to agree
5. Click the SEND button

We will email you (or your employer) with further instructions.

@ttmc i actually completed the form right after my PR per the contributing instructions, but have not received an email.

@morrme I saw this pull request before I saw that email. Sorry! I'll reply to your email ASAP.

This is to confirm that I agreed to and accepted the BigchainDB Individual Contributor Agreement at https://www.bigchaindb.com/cla/ and to represent and warrant that I have authority to do so.
