If you are doing the "basics", then keep in mind not everyone is using the newest update. Any scripting you may cover would have to have commands that all versions will have. Unless you are only covering a specific version.

Not quite. You can't release models in an FPM that belong to official packs, FPSC itself (stock models) or any models for sale. You can release models with the FPM if you made the models yourself and distribute it with the FPM. In other words, if my wife made the models/media for an FPM tutorial level and I made the FPM, I can provide both the FPM and the models/media. I could not make an FPM with Model Pack 8 and distribute any models/media from MP8 with the FPM.

There's no problem that can't be solved without applying a little scripting.
