For personal and regular creator accounts, OfficialMe is free to use.
OfficialMe only has fees for creators who want to monetize their content with subscriptions. If you signed up as a creator you can apply to have fan subscriptions so you can charge for monthly access to your content.
Paid creators don't pay anything until they start earning. We will then just take a small percentage of your subscriptions. The current fee is 18% of your subscription price plus payment processing fees. The payment processing fees are for the credit card transactions used to by the subscribers to signup to become a paid supporter.
