[Opensim-users] List of banned viewers for config files?

Sun Aug 19 15:26:46 UTC 2012

I recognize a number of those names, Fleep, and have now added your list to
my own.

Oh! And a bit of a self promoting plug here, speaking about viewers, I do
have a list of OpenSim compatible viewers, Misfit's Index of Viewers, or
MIV, for people to check out. I've listed a number of features as well as
homepages and download links.
http://excelsior-station.wikidot.com/misfit-s-index-of-viewers-miv Please
let me know of other, legitmate viewers that are publicly available, as
well as features you would like to see listed.
