A Jumble of Words is free to join, and participating will never cost money.
See that email field? That is completely optional. We will never force you to give us personal information. That's simply not what this website is about.
Even if you do give us your email, we will send you updates only as often as you want us to - and the default is none. We don't want to spam you, after all. Oh, and we will never share your email address with anyone or display it on your profile.
Everything you write on A Jumble of Words is private by default - for your eyes only. But it's easy to change this setting, if you want others to be able to read and comment on your work.
