You may notice some wonkiness - i'm just integrating the wordpress install and the xenforo install. Things may go funny for a little while or you may get some odd emails here and there as it syncs the accounts.
Was in london at the weekend and ended up being overcharged for a journey as we didn't touch in after the match due to the station being rammed and a train on the platform. You can set up a contactless account with TFL online which you can use for claiming back overpayment, including historic payments with the card.
I claimed back saturdays charge and another two were flagged for me to check which again I'd overpaid on. All three were refunded today so it's worth checking out if you think you may have missed touching in etc.
