Gilles, I PM-ed you my name for the github. Thank you for including me.
Also, if I can add to Filip's comment, the keep the lengths of the twisted data lines the same.
Regarding the github, I am far from expert but when you start changing code you should never do it on the master branch, i.e. start a new branch, do coding and when happy with it merge it. That way the overwriting code can be avoided. Also you can (somehow?) give me permissions to the repository which will give me the same rights as you. This will let me start a new branch and do changes there. You can always change branches and see what I am doing and otherwise. But if you give me permissions you lose 100% control
Right now I had to fork your code, do changes on my fork and do a pull request for you to review. It gets messy that way as you have seen.
Great work Brendan
Keep populating the board, you are almost there.
And that was a great shot of dark matter
Pat, I am waiting for approvals to join the Ukrainian forum.
By the way, some info for our European friends, I am in Perth which is at the moment 7h ahead of you. Few other guys are on the east coast of Australia which is 10h ahead of you.
