I think we started to deal with this, and I'm not sure what stage we're at.
We have 55 members on our membership list that have never posted, some having joined as early as 2005. Some were moved to a special "tempnopost" group, as can be seen by their yellow colour.
Was this in preparation for deleting them? There are some emails in the Admin email account that seem to be asking people if they still want to be active on b77.
Is this a work in progress that got interrupted?
