In my opinion, there is one blog type missing, or even a whole category, which I think is...

Photography

What I mean by this is in-game photography, like pictures of amazing building, or beautiful landscapes, or pictures of you and your friends, I think that you should also be allowed more pictures per submission (I think 50, compared to the regular 10), and that it should be a sub-category for blogs, although you may think differently. I just think that this is a wonderful idea and that it should be put into PMC. If someone else has already put this, then sorry, but I did not know, but thank you for you time and post what you think in the comments.

Sincerely,
