That method of finding friends is basically what I ended up doing. I was a bit flummoxed by DW importing my LJ friends list, but all the links are actually to LJ (which makes sense, how could it know who they are on DW?) so had to do the manual find as you said.

I've found a custom style for removing pink on my journal and reading page, but not other pages like settings etc (oh the actual posting page! That was the bugger). I'm sure I'll cope, and/or get up enough interest/time to make the effort to change it when it annoys me enough.
