Cool!

Hey, would you please add RegnmolNET to
https://tahoe-lafs.org/trac/tahoe-lafs/wiki/Grids . Maybe you could a table
with some columns like the (approximate) date the grid was constructed the
(approximate) number of users, etc.

Yes! I think this would be a very useful thing to have. I'm not sure if it
should be a standalone script or if it should be a feature of the Tahoe-LAFS
software.

Please see if one of these tickets:

https://tahoe-lafs.org/trac/tahoe-lafs/query?status=!closed&keywords=~ostrom&order=priority

Describes that feature already. If not, please create a new ticket and put
"ostrom" in the Keywords. Here's the wiki page on Ostrom:

https://tahoe-lafs.org/trac/tahoe-lafs/wiki/Ostrom

By the way, as I just mentioned on this mailing list recently, most
Friend-Grids fail, as far as I have heard. I suspect that the lack of this sort
of monitoring/transparency/visualization/socialization/Ostromism feature is one
of the reasons for such failures.
