A large number of my readers and members of TradeShark Tennis are Polish speakers. The site uses Google Translate but a translation by a native speaker is obviously better.
www.traderzy.pl Is a very popular site and one of the largest sports trading sites in Central Europe. The website is in Polish and has users from Croatia, Slovacia, Ukrainien, Belarus, Czech and Litvia.
They offered to translate the members area and that work has started. Members will see a Polish flag next to the sections that have been done so far. Click the flag to go to the translated page.
Many thanks to Traderzy.pl for the translations.
