Not a programmer at the level this work requires - but very keen to see it happen along the lines described. I am willing to help extensively as a tester and 'user advocate'.
I have 5 linked GEDCOMs on my own web site, ranging from very small to large, plus local test facilities. I also host the www.PGVThemes.com web site. A PGV user since 2005 (ver 3.2).
I am a regular contributor to PGVs Help forum, as 'kiwi_pgv'.
