- In Comm, each community is hosted on somebody's keyserver. - You can set up a keyserver on your laptop or in the cloud. - Comm won't host your keyserver for you. (We don't want to have access to your data!) - You don't need a keyserver to join a community, but you do need one to create a community. Keyservers enable us to offer the sort of sophisticated feature set that typically relies on corporate servers on the cloud, without sacrificing the privacy of our users. - Each community on Comm contains a tree structure of chat threads. Our threads are sort of like channels in Discord, but they can be nested inside each other. - Comm supports "sidebars", which are sort of like threads in Slack. Sidebars are created in response to a message in a parent thread. - Along with the default chat functionality, Comm also supports a library of apps to customize your community. We're launching with a Calendar app, and have more apps in the pipeline!

Read full description

Qwantum Private Messaging is a cloud-based application designed to enable its users with the ability to encrypt and decrypt sensitive data. The application works with MagTek Card Readers and Qwantum Cards to provide a powerful authentication experience that does not rely on usernames and passwords. Qwantum Private Messaging is organized as a club so that it can grow and flourish by attracting like-minded professionals who see value in privacy, do not intend to use the service for unscrupulous activities, have business needs to establish the authenticity and integrity of the documents, and objects they rely on, and desire to trust with confidence those with whom they share sensitive or confidential information. To create a Private Message, simply glide your Qwantum Card through your MagTek reader or use a Member or Guest Token. Once authenticated, you can create your message, choose to add an optional attachment, designate your recipient(s), set an expiration date, and choose the level of audit detail you desire, then press email or download. The Private Message is created, encrypted, and delivered to the designated recipients. Our mission is to build a network of trust based on these timeless principles: Privacy, Integrity, and Authenticity.
