Eileen,
I agree there should be a few moments after the game to congratulate the winner, schedule another game, et al. The abruptness is a bit disarming.
As for the two accounts, please contact the folks at members@worldgolftour.com and let them know that there are two of you on the same machine. I do not know if it's possible to compete against each other,.. that's a good question for them.
The main reason you would want to let WGT know about the accounts is that if one remains in the lower tiers and actually wins money/credits, and the other account is Pro/Master, it really looks like someone is sand-bagging and stealing the wins. Let them know soonest.
Have a nice day!
