Gidday Kimmyann, I am not a mod, just a forum member. I had ur problem and it took me a couple of days to figure it out so here goes!
My problem was that I couldn't get far enough down the neighbours page to add my new friends. If that is ur problem too then here's what I learnt...
I had to delete non-active neighbours to make enough room down the bottom for my new friends to show up. I started with the ones who just say FaceBook user cos my understanding is that those people have de-activated their FB account, so I was safe in getting rid of them.
Then I made a note of the others who were inactive. I then considered if I wanted to keep them as friends on facebook. If I did want to keep them I left them as neighbours. But all the ones that I could live without I then unfriended in FB.
Now here's where it got weird for me... FB took overnight to make those neighs that I had unfriended disappear!
Another thing I encountered from messing about in that neighbours page (which I understand is a facebook page, not FT), is that my lappy didn't like it at all!
Sometimes it would freeze or mini-freeze lots. I had to restart my lappy and sometimes that didn't help much.
So I switched my lappy off overnight and that really helped.
Guess I'm saying that it was a real task to achieve adding my new neighbours but it was worth it in the end. I've ended up with more active neighbours than I've had for a long time and my neighbours page is a lot more up to date.
If any of this advice is wrong I stand to be corrected. I just thought outside the square and added 2 and 2 together. Oh, and I'm good at mixed metaphors too hehehe
Would love to know an easier way if there is one!
