Now, I'm not sure if this belongs here but I'd like to make a quick comment on Serebii's use of the word "whom". This word is something most people don't use very often so it's understandable that its use might be a little confusing, but the word "whom" is only to be used when it is the object (direct or indirect) of a verb. The homepage oftentimes uses this word when it is the subject of a verb, and this is a grammatical error. For instance, from today's update: "You may encounter Celebi whom will take you in the past to clear missions." This "whom" should be "who" because it is referring to Celebi, which is the subject of the verb "will" in the sentence. If the sentence were, for example, "You may encounter Celebi to whom you would give a note", "whom" would be correct because it is the object of the verb "to give".
I have noticed this mistake frequently in Serebii's posts. If you find the usage of this word confusing you could perhaps simply forgo the use of the word altogether, as many people do.
