Grammar post

I seem to have a hard time with remembering all the rules with commas. I guess that I'm so worried about having them placed in the correct spot that I sometimes misplace them. I usually have to pull the rules up when going over my paper so that i make sure I have obeyed the comma laws. The easiest one is when I'm reading i look for breathing points, but that does not always work. There is also using a comma when you are using a series of something. Example: My dog has many talents, fetch, begging, dancing, staying, and sitting.I found a site that I thought was helpful. It has a list of punctuations and rules that go with them. HERE check it out!
