goto the elf ape spawn near the bridge in ape city, theres always a party there. or try going to bird island and team with an archer. those are the best places to level fast.
basically just remember when looking for a plvl team you are a newb but it doesnt mean you have to act like a n00b. if you walk around begging "plvl plsss plvl plssss" then you will get killed. also dont call the team leader "mastor". its lame and self degrading and no one likes it.
check out the plvl guides on the CO website, they are useful.
