Why has the opening post to the primary maths methods thread been deleted?

[Feenie]

It's very curious, and I have would like to know why, please!

Hi Feenie, it was deleted because there were a few reports suspecting it of being a kind of advertising, which we don't allow.
We have posted on the thread saying that, if this isn't the case, we'll get tech to put the post back first thing tomorrow.

Thanks Catherine - we don't think the opening post had anything like that in it, but a post further down the thread might well have.
