Hi. Sorry for the late notice, but I'm going out tomorrow and I don't know what time I'll be leaving/what time I will be back, so I'll have to move our 'trade time' to around 8pm GMT just in case I'm not home in time! Sorry for any inconvenience this may cause.
If 8pm GMT doesn't work for you, I'll say 7pm GMT-9pm GMT as it's just easier to do trades after I would've had dinner around 6/6.30pm GMT.
