sometimes game makers say "free" to get ppl to sign up. By what they say in piratesonline.com is that you must pay to get full membership. You can play a free version, with adds, and less options. Also, wikipedia is not ALWAYS accurate 100% of the time, anybody could have put that, to fool people, or they miss undestood it. You can't ALWAYS 100% trust what any wiki says. Disneyonlineworlds.com is based on facts, but sometimes things are not updated when something changes, usually a small thing. The editors at the wiki try very hard to keep it updated, though based on facts.
So people might get the wrong idea. I might be wrong about wikipedia, because it might be right. So this might be right, but I really don't think everybody will get a free account. Some online games give free memberships to the first so many ppl or for a limited time (like a month). You might be right and I might be wrong we won't know until it's official on the site itself.
