h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I went to look at the page of a researcher with a name I didn't recognise. U3294375

I realised he/she was a newbie but didn't appear to have been aced, despite having been here a few weeks, so I tried to post a welcome message. Every time I try, it tells me I'm not signed in and can't post until I am, I sign in, try again, and am told I'm not signed in!

Can someone else try? It's not a general bug because I can post to other convos on my list.

It's most probably a researcher from another messageboard, that's why you can't leave a message, so don't worry about that

Either from radio1 or 606, according to where he posted

Ok, it just seems weird. They have posted things here. I didn't realise it worked like that.

Oh, I didn't notice that.

No, it's not that obvious, because most postings shown are on h2. Friendslist leads to somebody from 606.
Whenever youcan't leave a message, it's a clear indication that the researcher has signed up with another message board.

What's though, is, that he's shown on the h2 online list

That's probably because he's posted on a h2g2 convo thread, although I haven't time to sorry

Well, that would explain it. I always thought the list would only show hootoozins, though

Traveller in Time on his head
"Everyone logged in to the Single Sign On System and visiting HooToo (posting or just reading) will show up on the < <./>online?thissite=1</.> >
Have a look at < <./>/dna/collective/U3294375</.> >, below their introduction Collective shows what site the account belongs to. More or less exacly the kind of message I am asking for for about a year by now. "

He's a 606 user. And the h2g2 who's online list shows users from all DNA sites and messageboards at the moment. It hasn't been changed to show only h2g2 users.

A succession of modifications, to the way the dna software shows things, has combined to lead to this confusion being common.

1. The removal of the PS A-number from display in the article list (which would have revealed the site).

2. The redirection of A-numbers to U-numbers.

3. The display of U and its attached forums in any sub-site skin from which they are approached, rather than in the native one.

4. The introduction of SSO in the first place - breaking the original, genuinely single sign-on!

5. The ongoing problem of unhelpful and inappropriate error messages all over the site.

Thanks everyone!
