Cost - Free
Parents Permission Policy - I could not find anything about Newblog's policy on minors.
Profile Page - Your profile page will of course include your profile photo and anything you included in your profile bio. It will also have links to your photo album and your blog. Your friends list will be shown and your calendar and comments will show on your profile page too. It's a pretty simple profile page but it shows off who you are with your friends list, photo album and blog.
Photos - You can upload up to 20 photos to your Newblog site. Add captions to each one so your readers will know what they are. Photos should be smaller than 250KB and must be in either BMP, GIF, JPG or PNG format. Of course you can only upload photos that you have permission to upload or that you own. There are more rules to adding photos that you need to follow. On top of the photo album you can also add a photo of yourself to your profile page.
Blog - Create catagories for your blog posts. Make your blog look the way you want it to using templates, editing the template or using HTML and CSS.
Advanced Design - You can use HTML and CSS in your custom bio fields and in your blog or profile page. There are templates that you can use if you want or you can create your own using HTML and CSS.
