I've been using familysearch.org without registering - just finding census records, etc. I've been using them to refine dates, get detailed lists of siblings, etc. And I've been using the citations given by familysearch in my source sections.
Today I got into a new part of familysearch.org that required me to sign up for a free membership. When doing so I had to read the terms and conditions. There I found a prohibition to copying information from their site to other places. I am not a lawyer, but it appeared to me that it *might* prohibit the sort of use I have. But I gather that it is a major source for this site, so presumably it isn't prohibited.
Can someone explain what usage from there is/isn't permitted here, and (roughly) why that is allowed?
