OK. I'm officially an idiot. I created a WCG account. I can add it to BOINC. Haven't actually done any workunits. How do I add it to BoincStats?

When did you
a ) create it and
b ) reported your first WU and got credits/points and
c ) are you using BAM! ?

WCG only exports it's numbers twice per day, iirc at noon and midnight UTC. After that, go along this lines in the FAQ.

Thanks!

a) Created the account some time ago. One or two weeks.
b) My first WUs are listed on the 25th and 26th of July.
c) Am I using BAM!? Well, I guess that's the question really. My user profile is "ulfson", I can find myself listed with 2,390,659.60 credits and some activity of late, so I guess so.

What's going on is that under "My detailed stats/Project list" WCG is visible and the points reported, so I guess Boincstats is picking it up somehow. Under "My BAM! menu/My projects" it's not listed. If I go to "Sign-up for projects" and click "Add project" for WCG I get a laconic "-214" under "Last attempt". If I click "Create account" i get "No response from server".

Is the account maintained entirely separately from BOINCstats BAM!? With my other projects I can add membership to groups and so on in BOINCstats - don't seem to be able to for WCG.

That's right.
Unfortunately WCG doesn't support AMS like BAM! in the proper way, if in any.
You should be able to attach it to the account by "Sök konto" (not "Skapa konto" ) on the "Anslutning till projekt"-page, but that's all for WCG.
