The links in the top right corner are domains which in the short future will be maintained by regional partners, not ourself. With maintained we mean they provide news, competitions, moderation, advertisement, etc.
USSR is configured as a region. The region currently contains Russia (ru), Belarus (by), Ukrain (ua) and Kazachstan (kz). You can indeed also go to ru.hwbot.org, and it will display the news and competitions of the USSR region, but all rankings will be scoped to Russia instead of the old USSR.
The ro.hwbot.org is specifically for Romania, so that's a national partner. Links which are not published, eg be.hwbot.org, will display localised rankings, but not localised news or competitions as they are not maintained by a partner.
If you want to gain control over a region or nation, drop us a mail @ info@hwbot.org
