I copied the example helloYeller space-script block and corresponding template block into my space and hit ctrl+alt+r, but the template block just says Error: Unknown function: helloYeller.
I was successful with a registerCommand test, but not registerFunction. I mist be missing something somewhere…

Yes, this is because the website docs are inconsistent with the currently released version. I’ll do a release later today.

If you upgrade to 0.7.3 now it should all work as documented.
