Whole Game System is not very good with these leagues. Hopefully they will link it into Full Time at some point.
I do a few of these a season. Not necessarily BUCS but ESFA Academy games and struggle to find the league on whole game let alone the teams sometimes!
My game 2 weeks ago resulted in 3 cautions and straight red for VC. I went to upload the game to WGS, only to be able to find the away side, the home team were not in the list of available teams. Therefore, a quick phone call to local FA's and told them I would email them the details which they were happy with. They have not come back to me saying "don't do it this way".
