SOGo is used for accessing your mails via a webbrowser, adding and sharing your contacts or calendars. For a more in-depth documentation on SOGo please visit its [own documentation](http://wiki.sogo.nu/).
As of December 21 2018 we removed our custom themes due to complains about missing colors in some address book and calendar sections. Some other problems were still existing and would not be fixed in the near future (switching colors on login screen, for example).
