Actually, I'm going to merge this to move things forward, but please make an issue if you want it changing.

Ah, @AxelPetitt can you please sign the CLA?

[AxelPetitt]

Hello @frankharkins,
Our university just approved the signing of the CLA.
The repository I submitted is the public one but we are actually two contributors on that project. We each contributed ~1k LOC to the project. Should he also sign the CLA ?

[frankharkins]

No, just you signing is fine thanks – the CLA is just for the contribution to this repo (~10 LOC), it doesn't affect your project's code.
