It's tough with 8 people spread out over a range of XP!
If the whole group is at one level, say 8th, I see no reason not to start the new player out at the bottom of that level or one level below. I would think two levels below would be depressing to play unless they just leveled up, as if your being penalized for starting late.
In the end though, it really depends on a few thing:
-the player comming in (experienced, commited, etc.)
-the attitude of the group
-previous new players added, they started where?
One way to make someone grouchy is to start someone new at a higher level distance than what you started them at!
Last, I always ask the group "would you mind if" or "what do you suggest" and see the responses (everyone has email now). It's surprising how simple that makes my decision.
