[Opensim-users] llVolumeDetect

[Shaun T. Erickson]

I'm curious about something. Unless you have an old, original, Blamgate, 
made by Pathfinder Lester, then all other Blamgates are made by Shaun 
Emerald (me - I started with his and have since rewritten it 
completely). But neither his nor mine use llVolumeDetect() ...
