Insights: How to use Commas
This should probably be a paid-only post, I guess, but this is my page and I'll do what I want! 

Fundamental grammar stuff will also be free! I can't in good conscience charge for something I think everyone should know.

Anyways, check the attached file to get learnin'. If you can't open odt files with other word processors (I'm pretty sure you can, but I can't be certain) you can get LibreOffice for free!

I suppose you can also check out my currently-running  quests, Aliens Ruin Everything  and Hospitaller Quest (NSFW) to see more examples of comma usage.
