Hello maxcam,
meanderings ( the word should probably be " side tracked"
haha, then you are a true member of Rootschat!!
you asked about secure sites: back in the early 70's I "took over" the family tree from my paternal grandmother when computers were a room you walked into...
and then a few (10-15) years ago I passed on the mantle to my sister. She has published our tree on tribalpages (mentioned above) and also ancestry. We have also put our toes into Genes Reunited, an offshoot of friends reunited and one or two other sites.
Now, you will hear good and bad things about each and every site. A few years ago, for example, Ancestry was very keen to keep as many people as it could so it started to get a certain reputation for not wanting to let go if people wanted out when contacts became invasive. Those days have gone in my opinion and it is a safe, friendly and very very useful site in this day and age. Their costs are not bad either when you consider that the people (like you and me) who work for them also have to make a living, pay their mortgages and grocery bills, etc etc.
Also, Ancestry has a lot of good information which is very useful. A serious site that really does help its members.
Genes Reunited is newer than Ancestry but from what I hear/read on the internet, they are becoming friendlier, less fearful of losing out so not so grabbing as in the past. A lot of fellow Rootschatters like them.
Tribalpages? Seems a jolly nice site but one that we have never got into for no particular reason. It has nice trees but that seems to be that. I would love to hear more about Tribal from its fans. Hopefully it is a very useful site like Ancestry and that we have just missed out.
Other sites - well just ask others who know. I don't want to comment on what I haven't seen. And of course, do be circumspect but without being overly cautious and especially not paranoid. My sister would not have found nine tenths of what she has, had she been fearful of communicating with strangers on the web.
cheers, falcybe
