 This section gives an overview when which person became a member of our team and how IT4C became to be.
 
-It all began ~2017, when [Alex](people/alexander-friedland.md), who made the initial website for the DEMOCRACY project, met with [Ulf](people/ulf-gebhardt.md) in Karlsruhe to <!-- textlint-disable write-good-->evaluate<!-- textlint-enable write-good --> the state of election methods available in universities at given time.

 ## Human Connection
 
-Most of us met again 2019 at Human Connection. This time all as developers to <!-- textlint-disable write-good-->implement<!-- textlint-enable write-good --> the envisioned social network. [Wolle](people/wolfgang-huss.md) was first, followed by [Alex](people/alexander-friedland.md) and [Ulf](people/ulf-gebhardt.md). While Ulf left for DEMOCRACY again, Hannes volunteered and Moriz joined the Team, till the project ended 2020 as Human Connection and was transformed into *ocelot.social*.

 ## Ocelot.Social – End of Human Connection
 
-In the last quarter of 2020 Human Connection was ended as a project and the source code was republished under the name [ocelot.social](https://ocelot.social). [Wolle](people/wolfgang-huss.md), [Alex](people/alexander-friedland.md), [Ulf](people/ulf-gebhardt.md) and [Moriz](people/moriz-wahl.html) continued on the project and released wir.social to keep *ocelot.social* alive.
