I recently was surfing around and stumbled on a great forum about Poland called www.polishforums.com. It has an active community and the common language is English. There are threads about almost every topic. If you are interested in exploring Poland than the ‘experience Poland’ section is probably the most interesting. It also has an area about Poland Vacations and Travel where you can find a lot of usefull information.
