*sucks teeth*

I realised today that just clicking on "Add them as a friend" doesn't actually add them as a friend... There's a wee "Add" button way down under the page cut below a load of meaningless looking guff that looks it's something to do with user colours...  So sorry anyone I mistakenly didn't friend back!

After clicking insanely on just about every link for about 15 minutes, I finally found out how to see what communities people belong to.

And I accidentally found out that the list of people I'd be-friended is under Friends / Other Friends Tools > Manage Friends.

Argh, time for another drink, granddad...
