No, this isn't a whole new script, but just an idea I had.
To change the lookup function some, so it'll be "lookup($name,$noupdate=false)", so if $noupdate is true, it wont connect to FC server even if the char info is out of date.
This isn't really a revolutionary thing or anything like that, but might save some time during low priority lookups (like maybe alts list or such). Alts is actually the only place I can think of where it might be good to have, but maybe future things could benefit it too.
