Unire i team rimasti

Ciao vorrei riunire tutti i team rimasti o in rookie o in pro e' uguale, basta che siano tutte insieme. Altrimenti c'è il rischio di non divertirsi piu. 2 team solo non si può vedere. Abbiamo sbagliato noi all'inizio a mettere le promozioni

Hi Daniele
Please in the future post in this forum in English only, You can use a translator to do this. In the future your post will be moved to the Italian forum if this does not happen.
To answer your question this can not be done, the only way you can go up or down tiers in your league is through promotion or regulation. The easiest thing to do if you want to all stick together is start a new league with the promotions checked as off. Or you will have to wait till your friends promote.
