Yes! We’re constantly making the sites a better user experiences for you. We run a customized version of WordPress, the best and most widely used blogging software in the world by an enormous margin! We keep this continually updated and improving. You’ll always be cutting-edge in abilities, along with added bells and whistles you won’t have with a simple WordPress.com site (or any other blogging platform). That said, some extra features have a learning curve, for sure, but we offer plenty of documentation and you can always just ask for help. Also, you don’t have to turn any of them on and use them if you don’t want to—the basic setup is already thorough and amazing! It’s all completely up to you!
You will always hold all rights to the content published on your site. Your words and media will be your words and media. We’re not looking to sneakily take your content. On the TMM central site, the terms are that we receive all copyrights to content published there (though we co-grant you the use of it as well if you contributed it), but on your hosted network site, it’s all yours, all the time. This means, even if you leave, you can take it with you! We might cry a little, but we won’t fight you for it. We’re only here to help you.
