It's...kind of an unwritten rule, but it should probably be clarified in the forum's rules (I can edit them if you want me to, since I know you just kinda got WD thrown into your forum without knowing wtf goes on in there XD). WD is for advertising your own site and talking about webmastering in general. The official pokemon.com thread should probably go in Pokemon General.
I got a report saying that official sites aren't allowed, but I can't find anything in the rules that says talking about official sites isn't allowed in webmasters.
