the applicant makes the test. just like a hacker makes a test in the matrix. is the hacker somehow constrained from getting a teamwork benefit? no. no he isn't. because that would be an asinine interpretation of the rules.
who helps the applicant? why the group he's trying to join, of course. each of whom have the arcana skill, based on the fact that they tried to join the group.
Great, so even buying hits to save time the GM needs to decide the Arcana/Logic dp for all the members present to see how much they add, how many of those members are present and willing to help. Please note that by your interpretation, joining the Mystic Crusaders at 33 members is now a snap. At 1 hit apiece they just added 33 to the applicant's dice pool. That makes even the dumbest magician with the lamest Arcana skill (1+1) a shoe-in.
Reminds me of Animal House. "We need the dudes. Let him in." Talk about lowering the bar. Seriously, it's the applicant being tested for his worthiness to join the group. He's on his own.

and again, consider what a magic group is: they're a group dedicated to studying the deeper mysteries of magic (ie initiating). if you can't even write a damn spell down (or craft a proper sculpture, or whatever your tradition does to create spell formulae) then what the hell do you expect to contribute to such a group?
How about Ritual Spellcasting 6, a Manabolt spell for those harrowing journies to the metaplanes, dues, contacts, magical muscle, ward duties. I can go on. The initiatory "deeper mysteries of metamagic" and Arcana skill only cross paths a very few times EXCEPT that it is the skill used to join groups.
