The majority of your requests have already been made by other people. In the future, please check the [url=http://www.roleplayerguild.com/topics/2572/posts/ooc]big list of requests[/url] before making a new thread requesting things.

Most of your first three suggestions are things that users can already do in the Spam (formerly known as the Spam/[b]Forum Games[/b] section on old RPG, hint hint) or Member's Lounge areas (meant for socializing, which is where "ask me anything" and quizzes about forum users would fit). Games and the like are the purview of forum users to make of their own volition, not really things to request Mahz to make.

The ability to make polls has already been requested, but the above about games also applies to the fun and silly polls idea.

The Writer of the Month contest from old RPG will be returning at some point after Mahz gets around to making an Official Contests forum section. Other contests (unless they're informal fun things done in Spam or the Members Lounge) would have to be approved and officially sanctioned to go there, but it could happen. Contests to become a Comrade probably won't happen, because they only need a handful of people to do official Comrade duties and I seriously doubt that Guru (the moderator in charge of the Comrades) would recruit through contest rather than hand picking someone who would actually be good for the job.

Groups have been requested already.

Likes and dislikes tie into things Mahz has said before about wanting to integrate roleplayer information into the user profile, so that should be a thing at some point.

The what's new thing is a new request though, so I'll add that to the aforementioned big list.
