why do i get this on mumsnet competition entry forms?

[Doubtfuldaphne]

I'm signed in but get a message saying 'sorry this is not open to the public' or something similar.
I'm not the public, i'm a fully fledged MN'er!
Can I not enter MN competitions?

When a comp has finished a while ago it does generally say sorry this competition is over but the other day I went to one and noticed it had just expired and I got the same message as you, perhaps they have to take it down to judge it etc when its effectively offline to us?
