In Mighty Networks, both the webapp and the mobile app, let you connect to multiple networks/communities and simply switch between them by toggling a sliding menu from the left (beyond the current community menu)
Please impliment this feature as your platform is taking off and many people want to belong to multiple communities.
Doing so now is impossible and you can only have one community live on your phone at a time. On desktop its easy because you can just open a new tab, but that doesn't solve the mobile issue.
Thanks!
