@quozl can you please review this and a few other similar pull requests?

because, for the next set of pages to be moved, they are linked to pages above.
And having these merged, makes the job a bit less complex.

thanks :)

I'm not that familiar with the content. I'm hoping @walterbender will review since he is an activity maintainer for Turtle Art.

If the delay is causing you problems with complexity, combine your commits for all the pull requests into a branch and open a new pull request against that branch. Continue working on that branch for all Turtle Art changes until it is merged.

These are OK... But I cannot merge.

thank you for the tips :) I've opened #64 and will use the same to move pages of turtle-art tutorials henceforth.

But I cannot merge.

Permission issues; I believe.
probable solutions?

[quozl]

Oh, I guess because @godiard has not added @walterbender as collaborator. I hadn't thought of that, sorry.
