I thought Blizzforum was linked to the legacy sites, since way back when, I just noticed today I had to register with SCL. Wasn't there a way to use one account for every site? If not. I would like to suggest that.
Also I noticed WCL is just a picture, when I remember it used to be huge site for Warcraft 3. Did the site just go on hold for the Domain?
All of the legacy sites are currently going through some sort of redesign/reorganization. We'll steal a page from Blizz and say itll be done when its done.
