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.
