I have decided to make one new role called Comment Moderator. The purpose of this role is to look for inappropriate comments, and delete them. The reason I found this role necessary is because I want my site to be family friendly. I do not want use of inappropriate language commented throughout the site. I only gave this role the ability to manage comments, read, and nothing else, I do not want the role to have too much power.
As of right now, I plan on creating all the content on the webpage myself. I do not see the point yet in having many other roles. As the site continues to grow, I will find people I trust and give them new roles accordingly, such as publisher, administrator, etc. For now though, I have created a role with very little power, but that can also save me a lot of time.
