It's just like coryza wrote. We're doing the English version for now, but it doesn't mean we won't do other language versions. We'll see what the future will bring :)

As Cook say, there is no plans for other language versions. The biggest problem is not language of the site, but the fact that together with, for example, german site should come german versions of games. Which is very difficult, sometimes rights for translations, voices of certain versions are not in publisher's hands, and this makes buying rights for this games extremly difficult.
Which doesn't mean that some day...:-)
And some day we may also add feaature for linking external mods, language packs etc.
We already were disscussing it.

You know. Don't get me wrong. It is doable. Just pretty complicated (from legal/organization side). So we won't make it anytime soon as we have simpler stuff with higher priority on the list. You know our team less than 20 people, we need to choose priorities carefully:)
