Our league did it.
Plenty of players moving about. A lot was done through twitter and Facebook, someone would tell league there available, "league wouldnput itnon social media, clubs needingnplayers would contact.
Same other way, when a club was short they'd tell league, league would put it on social media and players would let them know there available.
Players moved about.
At the end of the season, they even allowed us to go on loan to other leagues. Due to early cancellations for weather. I went out on loan twice. One decent knock and one golden duck. Oh well.
One lad from our club went on loan to a clubs seconds, they were that impressed with him, there now paying him to be there paid pro next season! Paid off for that kid.
