The FreeStyle Canoeing web site is back up, fully functional and up to date. The current page doesn't have all the bells and whistles that the old one had but in my opinion, this is actually better. It's easier to find what you're looking for. All of the 2017 events are listed along with registration forms, descriptions etc.
Also of note:
The home page contains a link to the current issue of the Crosspost, which is the newsletter of the FreeStyle canoeing community.
