Subscription to announce and news feeds
announce@hifis.net should be advertised and link to subscribe should be provided as frequently as possible.
Currently positioned on main page ("NEWS" headline) and on top+bottom of the news site - always besides the RSS button.
@SpickerHZB @frust45 what do you think? Does the bell sign make sense...?
Furthermore, links mights be placed somewhere permanent? That would be in navigation bar.
Even more convenient subscription could be done with mailto-Link, added to FAQ
