[Qgis-user] New user problems

[Michael Treglia]

Also, for what it's worth, I developed the tutorial you're referencing (
http://mltconsecol.github.io/QGIS-Tutorial/).  Note-  it hasn't been
updated since version 2.12 (when I was last developing it for teaching
material) - thus, the operations should generally work as described, but
there may have been slight changes since 2.12.

If you notice anything that straight-up doesn't work the same or similar
with a newer version of QGIS, let me know directly (this e-mail address is
fine) or file it as a bug report in Github:
https://github.com/mltConsEcol/QGIS-Tutorial/issues

I have no immediate plans to update the tutorial, but will keep track of
these things and fix as I can/when I need to develop further for some
reason.

Cheers,
Mike
