We could change the default sort order but I'm not sure this would affect existing users. I admit it throws me off too if I'm on the forum but not logged into my account. I'll see if our system admin can do some internal tests.
this is only one element with this class combination on the page, then style will apply only to this twitter sidebar
i do not know nodebb but maybe it can generate automatically id for all elements?
Then life will be much easier ;-)
