Pvping on red99 is too risky and should be avoided at all costs.
These are the steps you need to perform when encountering another player:
1) See target
2) Is target in pvp range?
3) Is the target a known pal? Is the target naked (or do they just have shitty gear?)
4) Scroll up through the past 20 minutes of /ooc spam looking for a lns call in between the /wts CoS for 6k spam
5) Potentially, lns was called while you were zoning, so alt tab EQ and navigate your favorite internet browser to
http://www.r99pvp.net/ooc.php. Double check the last 20 minutes of /ooc for a lns call
6) If no lns call has been made, go to your start menu and get fraps running. PVP losses can affect short term memory resulting in posts similar to the one above.
7)
Start casting your first offensive spell.
