Have to pay more after subscription? – Xmind - Mind Map & Brainstorm Review

1. I have been using this app almost everyday. However, I don’t know all the functions of this App. Can you create a Facebook or Twitter group, so all users can join? If we have any questions, we can ask other users. 2. Annual subscription does not include all the features? I have to pay extra to use all the features?
