Thanks! I combined some of these commits, fixed formatting and punctuation errors, and merged into master. Fortunately, I was able to keep the author of the commits as Edlingeer through this procedure, as you can see in the repository's commit history. Unfortunately, because I did some rebasing, our repositories will now have diverged a bit. You can fetch master from this repo but you may not be able to easily merge it into your repository.

Next time I'll ask you to make the edits so any history conflicts are avoided.

Okay great. I'll do that as soon as possible and sorry for any inconvenience this may have caused. Have a nice day !
