Important notes

• If u specify u want to migrate avatars then a path to your MyBB forum is required also.
• Forums with a redirect hyperlink are skipped. Flarum doesn't support them (yet).
• A guest who created a MyBB post or thread will appear as a deleted user in Flarum and not specifically a "guest".
• The core BBcode extension should be enabled too.
