I went through the same thing and finally gave up. You're lucky they got back to you at all - the local area coordinator that I emailed never got back to me.
It shouldn't be that hard, but anyone that has ever dealt with the USTA for awhile knows that they are extraordinarily disorganized....and not very nice.
lol that sucks that you gave up. but come to think of it, this is the third time ive tried
i didnt give up this time because a friend of my bro is in it and i guess thats extra motivation. the other times i wouldve definitely joined if it was easier.
the coordinators i wouldnt say were rude at all but like you said, its like the organization is left up to the individual coordinator or subcoordinator. they need to streamline and systemize everything so that a player can get hooked up w/ a team w/ just a couple of clicks.
at this rate theyre losing alot of prospective players and make the ones who do go through all the hassle feel desperate.
