Monal IM - project moved

We recently started to migrate the App from Anu Pokharel‘s Apple account to Thilo Molitor‘s Apple account. As part of this transition we also deployed some new push servers to not let an old retired developer pay for the infrastructure needed for Monal. Coming along with this transition from the old developer team to the new one is our new clean website at https://monal-im.org/. From now on, the old blog at https://monal....
