It's a very good add-on that they've created for Black and White. It's not the best it could be, but it's definitely a step up from the Pokewalker.

However, I'm still not too keen on the hour limit for the Dream World, what with the fact that on my computer, I get a lot of lag, likely because said computer is near-obsolete, if it isn't already, and is probably over 7 years old. =P

However, the Global Link in general is pretty cool, though there are still some glitches that can be seen, which will hopefully be fixed sometime in the future. And EZ Mail is fail. Which also rhymes. =P Worse than MLN's messaging system, as in even more restrictive. Heck; even the mail system in the games is better. xD

The Global Battle Union is pretty cool; though I haven't gotten a chance to actively test it just yet... partly because I'm still reworking my team. =P

However, I do believe that the Dream World interface could be updated, and that the profile part of the main page could be redesigned; I don't care if this is the second time it's done, it's missing key info. =P For one, it doesn't tell you if there's any new messages(And what with it being so restrictive, you're not likely to check it actively); and there's no notice in the Dream World or on the main page that someone wishes to add you to the Dream Pal Roster... Someone sent me a request last night, and I didn't see it until after I had already finished up in the Dream World(Due to that silly hour limit). Now I have to wait for tonight for that.

Overall, it's a very nice application; however... It needs to be expanded when the next games come out or sooner, that's for sure.
