[Opensim-dev] Feature Request: osAvatarSit(key avatar, key object, integer options)

[Justin Clark-Casey]

Vegaslon and others contributed an osForceOtherSit() patch in git master commit 00b23e51aecab7902f0fe0a0b138698ad28caea2 
which I think does what you need.  Vegaslon then documented it at [1].
