Yes, sorry. My blog posting linked (and still does, I can't change
that) to the version of the map which the project updates weekly.
Since I just changed it yesterday it won't update until
Wednesday/early Tuesday. Here are updated versions:

Tristan da Cunha & The Settlement:
http://openstreetmap.org/?lat=-37.0787&lon=-12.2944&zoom=14&layers=0B00FTF
Inaccessible Island:
http://openstreetmap.org/?lat=-37.2998&lon=-12.6768&zoom=14&layers=0B00FTF
Nightingale/Middle/Stoltenhoff:
http://openstreetmap.org/?lat=-37.414&lon=-12.4778&zoom=14&layers=0B00FTF
Gough Island: 
http://openstreetmap.org/?lat=-40.3146&lon=-9.9446&zoom=13&layers=0B00FTF

What I've done is relatively limited, I've improved the definition of
the coastline from NASA satellite imagery, traced some (but not all)
of the streams/rivers on the islands, and added locality names seen on
this map: http://en.wikipedia.org/wiki/File:Tristan_Map.png

That's interesting, although in all likelyhood it's not data that can
be used for OSM, to quote the project charter:

   OpenStreetMap creates and provides free geographic data such as
street maps to anyone
   who wants them. The project was started because most maps you think
of as free actually
   have legal or technical restrictions on their use, holding back
people from using them in
   creative, productive, or unexpected ways.

Usually such map data is under restricted terms which prevent it from
being used in OSm, there's some further info on this in the Legal FAQ:

http://wiki.openstreetmap.org/wiki/Legal_FAQ

However, it may well be that you have existing maps, digital or
otherwise, which you have the right to license under the license OSM
uses, this was the case with the Isle of Man for instance where the
local government could license their map data for use in OSM, with
good results:

My knowledge of hydrographic features of the Atlantic fails me yet
again, thanks for correcting that:)

Getting a contact locally that could survey using a GPS would be
ideal. The reason I contacted you and the other address I mailed is
because I found the contact details on the tristandc.com website and I
didn't know who else to contact.

Is there someone else on-site I should be in contact with?
