Your name won't clash as long as you're the only one on Team 10. It takes 6-9 hours for the stats to update (i.e. if you submit something at 10am, it will take until 6pm for the stats to indicate the work done for "12pm" (noon), which is the timeframe between 9am and 12 noon.
What are you folding on? You'll want to use the right client. For GPU there's just the one AFAIK, but for CPU there's the older single-core clients, or newer SMP clients which produce much more PPD if your CPU's fast enough (say 1.5GHz or faster, I'm sure someone will correct me on this if I'm wrong). And if your CPU's say 2GHz dual-core or faster, you'll get most points by running SMP with a -advmethods parameter (this will allow you to use newer A3 work units, which give a bonus for the earlier you complete them).
Good to have you on board! We're a bit short on the weekly Folding News at the moment, but I'm sure it'll return at some point.
