as I could not reach Ulminia (while not knowing, that he was in hospital), I tried to modify Guild Roster 1.72 myself to work as a public roster. The Result can be found here: http://wow3.deswahnsinns.de/
Please be so kind and upload your data and test everything you can find.
Bug Reports and Praise may be left in this thread.
I still have to make some cosmetic changes as "Name, Copyright, "[guildName Roster]" and I also have to adapt the installer. If "all" bugs are found and everyone is happy, I'll release it to the public.
