Manaleak.com is a Magic site/store based in the UK, with a huge selection of singles and all that jazz.
But the big thing is that Manaleak is also home to mtgUK, a large writing community full of tournament reports, innovative decklists, format analysis, and in general some pretty great articles. And I mean really good, because now I'm one of 'em. So if you've been paying attention to my site even though you're in the UK, or if you're a fellow statesman that's just in search of some more great articles, then go ahead and check 'em out. I guess it really doesn't matter where you hail, as long as you're a part of the magic community there should be something there to interest you.
