Please note that feed from HU appears on a number of sites. If you post with information that gives personal information - which could involve your location - that information could be visible well beyond this community.
When you create a post you can lock the post to restrict it to just members of the community by clicking the radio button under Who can see my post?
Please also note that you should not personal details of other individuals on this site - such as names, addresses and emails.
Exceptions would be quoting of names in relation to published research or references to specific support sights where the information is in the public domain - though the preference would be to refer people to the relevant site rather than quoting the individuals name/details.
