A club is focused on a topic of general interest that we don't already cover. For example, you could have a stamp collecting club. A blog is for updates related to you and can be about anything. It is similar to having your own website. However, no personal information is allowed.
Advice columns are what they sound like and devoted to giving advice when users ask for them. You can also give advice without a user having to ask for it, such as how to make friends, do something better, etc.
Let us know what you want and we will add them.
