In order to make Polish topics invisible, you need to apply to English-only usergroup. You can do this via User Control Panel located in upper-right part of forum interface, just under the banner. English-only usergroup does not require any validation, so as soon as you join it, polish topics become invisible. If for any reasons you want to see them again - just quit this group.

c mon crow, why would I want to make polish topics invisible hehe, your language is interesting so I would rather translate them instead of ignoring that big part of this forum =P

Kirky.

It was made this way for the foreigners comfort. It must be hard to find International Sections with all those polish forums visible. Anyway if you want to learn our language then it is nice to hear ;].
