When you have an account change, let's say you sign in to a new SE site, the Network Profile should immediately add such a forum to your list of the forums to show that you belong to that new forum.
My question was migrated to ServerFault and after that I immediately signed in to that new site - and now on my account there is a question and appropriate badges etc. On my Network Profile there still did not appear any new forum link under the accounts tab.
What was wrong / What is the actual question?
On Network Profile there should be visible all my sites where I am in, but the newest - ServerFault - is missing. I see this as a bug, because my profile keeps out of date of my current status on SE.
btw. This is my first question on meta ServerFault - this should be added on the list also soon :) Also, this might be due to slow aggregation, but then: you could enhance it then.
