Does anyone know any previous winners and the seasons they won?

Hard to say really but some users have pictures on their profiles stating when they won the event.

In my view runners should keep a record so players can keep track

Something like this: http://funkysnookerclanleague.weebly.com/history.html

I won uk last season it was run and 9 ball season before that after tinie deactivated

Pretty sure i've won 9 ball twice. There was a history section on the FCL and FBL sites but they seem to have gone :o

FCL had a lot of its old threads deleted as well, so you would have to look through a lot of very old clan threads to find out.
