There are some technical problems with joining the mini-league but there are two fixes, either of which should get you in.
Dan has found that this works: when you paste in the code, delete the 8th character (the cross kind of yoke) and replace it with a lower case x.
Dan’s now inside the tent so he knows what he’s talking about (thank you, Dan). Try this fix first and see if this gets you sorted.
If it doesn’t, drop me an email asap at email@example.com and I’ll send you an invite via the Face the Ball site (which is the old way we used to do this). That should definitely work.
Hopefully, we’ll get everyone sorted via either method above.
