Who gives crap about an oxford comma? Im trying to.

I have read a couple posts by others and seems like commas are a good place to start. I have trouble with run on sentances, so hopefully I can learn something from this website I found.

First here are a couple rules Im going to try to remember. When you use a comma to connect two independent clauses, it must be accompanied by a little conjunction. Even short sentances can have problems with them if not properly placed with a comma. These rules make sense when I do research on how to use them, but the problem I have is when I am doing the writing and trying to remember all the rules I need to do. So hopefully this will help.
