Thank you both! I began to wonder if I was being picky, but I really was upset at the sight of it.
Only problem is that I'm totally non-techy and transferring GedComs etc is a bit of a baffling prospect. I've now realised, too late, the danger of having all your tree on someone's site so will need to find a good programme to rebuild the tree somewhere where it won't be mucked about with by web designers.
If anyone has any tips or advice, they'll be much appreciated.
