Given the numbers of shareholders of Cellmid by country that was posted here recently by our good friend DB (who has since gone AWOL) I think probably one hour on the phone would probably get to most of them.
The one in Ghana might be a bit difficult but I cant see three in the US and one in Germany being a problem.
With regards to DB and his twitter feeds:
It has gone very quiet in this regard.
Perhaps he is getting himself into shape running up and down the stairs ( if any) at the share registry.
