Unable to get in to "Forum preferences"

[PillowySoft]

I'm using Mumsnet on both my phone and my computer.
On my phone, I can find a link for "forum preferences" but when I click on it, it just brings up an Oops page to say "we can't find the page you were looking for". On the computer, I can't even find that link anywhere.

I remember we used to be able to do things like change the colour of our own / OPs posts etc, and that is what I want to do. Currently all posts appear as the same colour and I'd prefer to be able to have the OP posts in another colour.

Any help please?

Hi OP
That sounds like one of the features only available to accounts over a certain age.

We're not sure why it's a broken link for you! What browser is it you're using and can you try this: www.mumsnet.com/Talk?call=Preferences

Thank you. My account had some problems (logged me out and I couldn't seem to get back in so made a new account) so that might explain things, if it's a feature for older accounts only.
That link does work for me. I'm on Safari, on an iPhone and Macbook.
