I like the relationship charts and wish more people would put them on their
sites. It is something that really enlightened non-technical members (almost
all) in my project. It became a chore when they were not generated

For those with FTM (at least the older versions) I use this method. I enter
the male lineages of project members. FTM allows 3 different colors
according to sex. More colors actually make it confusing.

I mark each participant and ancestor who has the ancesstral haplotype (known
by pass-through) as male. I mark the ancestors whose haplotypes have been
determined (by triangulation or pass-through) as female. I mark those whose
haplotype has not been determined as ?.

I enter the mutation that each carries as a fact. If it is uncertain, I add
a ? to the possible mutation.

When printing out the chart, I print it to tabloid to try to get it on one
page. I then crop it with Acrobat.
