well i think the site is very good to learn, have a lot of tools to practice the earing and reading, mixing all of it whith funy pics and interesting thems and news. it has a great way to combinate the learning with a site that shows actuality and news.
it also hasa lot of gramatic's tools to help the visitor to learn, or grow up it's knowledge.
but, i think it has a level a little hard, i mean i think not everyone could get into the site and learn like ohters. it needs a good visitor's english's level cause the shape of the site is like all others, and the visitor has to know what he wants to get if, or he has to know enough english to navigate too well to find what hi needs and could learn.
but still i belive that this is a BBC´s good wise move cause this way it spread it's horrizons beyond of giveing information, reaching the international languge's learning.

well i liked a lot the part where it teach the phrasals, cause it have been one of my worst problems speaking english, so i feel it gonna help me too much, and so.. it´s a good site
