Coooooieee Mumsnet! Why can I not advanced search other posters?

[AmazingBouncingFerret]

It just keeps coming up error.

How will I ever complete my nefarious plans if I can't advanced search??

Me neither ABF.

I've just advanced searched you, Sparkling - just to test - and it came up with the goods!

(I am on a desktop using Firefox)

I just did ABF no problem.

Are you spelling the username correctly?

I can now but I couldnt earlier so perhaps tech have mended it.

It's back. And my search was very enlightening.

Is this one of those "searching iother poster" lies?

Gwan, ABF, admit it, you were Vanity Searching weren't ya?

I am now vvvv worried by sparkling's enlightened search

And I wanna know what 'vanity searching is', please?
