Just a quick note: I'm working on improving the community blogging and profile pages this week, so hit me up with your suggestions! Currently we support BBcode images and formatting, so you can make the sidebar of your blog profile look like anything you'd like. You also have your own private wall for comments as a tab, which we'll be adding some moderation features for you shortly.
Photos are automatically scaled to 275px, so no need to worry about size. Just put your favorite toys, mugshots, or collections in there and it should look great!
Please let me know what other features you'd like.
