Note that Etherpad is publicly accessible and linked to from the workshop website

We might want to add a note to [the link to the Etherpad](https://github.com/carpentries/training-template/blob/60d457cb560a1c2f4d559cc11579af2d8e0d0ac2/index.md?plain=1#L383) that it is publicly accessible. You only need the link and it is linked to from the workshop website. This should be made clear from the beginning, since trainees add their names, email addresses (though often institutional addresses), and personal opinions, stories and similar information to the Etherpad.

A similar note should be added to the top of the Etherpad template itself (where is the source for that?). Currently, there is a remark at the top that reads “Use of this service is restricted to members of The Carpentries community; this is not for general purpose use (for that, try etherpad.wikimedia.org).” The first sentence might be misunderstood to mean that no one else can access. Adding another item to the list of remarks could clarify that.

There might be more locations in the Carpentries documentation where this should be mentioned. For others, like the sign-up sheets for TD for example, it might not be necessary, since it is more obvious and the information provided is less personal.
