[Base for discussion on Loomio](https://www.loomio.org/d/ezlIV5rN/add-tos-and-pp-documents-for-podmins-to-use?proposal=k0LZg1M9#comment-128186).

So yeah, if enabled (default false), /terms route will work and contain either the basic template (default.haml) or custom written by podmin (terms.haml). Same templates are used for mobile too - we shouldn't duplicate these I think.

Also I'm sceptical whether there is need to allow somehow creating different language versions. Podmin can write it in whatever language they want or in different languages.

No tests yet, should probably write something for the setting <-> route functionality. Also is this as a feature something we want? Also the base template would need some discussion.

The terms are from [here](https://github.com/jaywink/terms-of-service) - though a little modified in this pull. I'm going to just delete that old repo. I've taken a print out from my local dev box for a little more convenient viewing :) [Check it out here](https://cloud.jasonrobinson.me/public.php?service=files&t=5e0e94be26f0a11b4a810d2bc72c5993).
Well there is the "governing law" regarding that to specify which law the ToS follows. But I know, I'm not a lawyer, I'm pretty sure to do things "right" one would need an army of them. This however has nothing to do with being US based imho, even if App.net is.

Basically this would be quite a light ToS since it would unlikely be totally law proof. But it would still be better than nothing - and since pods can write their own at least there is the "you accept the ToS by signing up" - which is what is missing now. *That* imho is the important part anyway.
