On April 26th, I e-mailed admin to change my e-mail address - I had forgotten that I could do this in Control Panel/Settings.
I was immediately 'de-activated'. The <admin@stepwagonclub.co.uk> address just produced an auto-reply saying that my message would be collected eventually.
It has taken until today for this to be sorted out with the help of Vantastic and his contact with Simon via Facebook. I think Simon had to 'deconstruct' my membership details and recreate them.
Nonetheless, it's nice to be back.
