How do I say “Yes, I realise that you don’t allow a member has/have more than an account.”?

Thanks very much.

I am quite surprised about this something strange. Why did you answer and then edited what you answered? I quite disagree with such a way…> I think that a feature should have been added to this forum to keep a member’s last reply at least. Because such is wasting for time only. If a member has been answered for his questions and when he return, he will find all his reply have been edited or removed. I would dare to say this is stupidity.
