@organicmaps As others already stated: there is no need for you to create another account on another instance because your instance makes new accs invite-only.
Additionally: there is a function in mastodon to move your existing account to another instance and take all your followers with you.
And lastly: if you move your account to another instance please choose any other instance than the behemoth that has gotten too big for its own good and too big for a federated mastodon world in general.
