Land of NoR (LoN), a Second Life RPG, has been working on an improved combat and RP system meter. The one in use is called WARPS, standing for Weapons and Role Play System. In July use of the experimental XRPS version of WARPS started. There are several changes being tested and several questions have come up.
You can follow the discussion in the Land of NoR forum.
If you have not noticed, going into SPAR (/9 spar) forces a save of meter stats. That is important to know as the meter only saves every so often. A SL or viewer crash or other forced relog can possibly force your meter back to the last saved status. Going into spar and back to combat status does a save and reload of meter stats.
