Hi
Not really to split the load, though it's part of the idea.
This is the scenario I was thinking about. Lets say my website sells Videos & CDs and so I want to create a few forums, ie "New Videos, DVDs, Actors, Actresses, Genres, CDs, Male Singers, Female Singers, Customer Service, etc.." That's alot of forums. So instead of having all the forums reside on one DB, wouldn't it be easier to create a seperate DB for each forum, that way if one of the DBs in MySql gets corrupted, it woulnt affect the other DBs.
Just my $.02
