Bulgarian Forum

The official Bulgarian forum can be found in Hattrick'org's Conference. The official language is Bulgarian.

BG-Liga

The first unofficial Bulgarian forum is BG-Liga, which started in the summer of 2002 - a few months before the Bulgarian league was created. The site has gone through several versions, but its forum used to be by far the most active Bulgarian place for discussing Hattrick.org.

Hattrick.Formenos

Hattrick.Formenos was created as a protest against the mass cheating of the users of BG-Liga. After the other forum lost its founder and some of its most vocal members because their teams were locked for cheating, a point was proven. Nowadays (as of November 2005) Hattrick.Formenos is the most popular Bulgarian offsite Hattrick community.

IRC

There are at least a couple of Internet Relay Chat channels that serve Bulgarian users. They are #hattrick.formenos and #hattrick and are accessible through all servers that are part of the UniBG system, e.g. irc.telecoms.bg.
