Roger,
Most of the CoM members are members of the Forum, and their accounts are tagged as "Com member", but its as a secondary group, and not their main group.
The search doesn't seem to find them because "Com Member" is their secondary group, rather than primary group.
The same applies if you search "moderators" for me, as my primary group is "administrators", so I dont show up in a "moderators" search, even though "moderator" is my secondary group
The CoM members who are on the forum are Chris Gunby (Triumph948), Nigel Hill (Nigel Hill), Tom Hartley (Tom Hartley), and Jane Rowley (Jane)
