Scripts that processes the join form

Which scripts processes the join form and creates the entries in the database?

I never got an answer on this.

can you explain what your trying to do or want done

I might want to do some extra processing on certain fields before they are stored in the database.

Check out the registerMember function found in inc/classes/BxDolJoinProcessor.php

Thanks Modzz, that should have popped out at me.  What is the old adage, "if it was a snake it would have bitten me."
