What have I done?

I don't get any colours on my iPad or my laptop apart from the admins posts which are green

Curiouser and curiouser! I now have pale blue shading to my OP on page 2 - not on the original post, just the subsequent header repeat. And I'm still on my laptop. And I've just checked threads started by other GNers - the same thing has happened there. They've gone from green OP on every page last week to no colour at the weekend to pale blue now on every page except the first! Subsequent posts by the OP in the body of the thread are still colourless though.

I am totally

Me too, I was missing the green background to the OP. On mobile and tablet the blue background for own posts is a help, too.

In fact, I find the scrolling up and down to find a post which either I have written myself, or which someone refers to at a later date very annoying.

On another forum I have been on sind 2000, which has been going since 1999, we have a side bar on each conversation, listing the posters, so if you want to refer back to a previous post, you just have to click on that, and are taken there immediately. On Gransnet, which must be much newer than 2000, it's far more complicated, and by the time you've found what you were looking for, you've forgotten why you were looking for it.

I am wondering about this. I've just posted two messages (from my laptop, old Windows) on another thread and while I typed them in an ordinary white box they have both come up on the page in green!
Not awfully keen on green - they're drawing attention to themselves in much too showy a fashion. When I click this I'm wondering what will happen.
