My word about
WordPress is a very nice site and has a lot of Club Penguin blog made by a lot of WP users
However I cannot name them all.
WP is a bit hard to use if your new here but theres a lot of surport @ the forums
Thers a lot of volenteers, a lot of times they solve your problem about 5 mins after you add a topic (that is if your at my time zone)
Its a great Blogging servce
