You'll have lots of questions, for sure (ok I am getting that from my students, napewno!) but searching the topics here will help you, there's lots of very helpful people and lots of advice from people who know a lot more than me (including the wonderful MagdalenaG :) ).
Just do my best to help...thank you very much !
In relation to Sky TV ,you can actually get Sky from a company called Sky Satellite services who are based in Warsaw. They supply sky box, dish & installation. Thy are very reliable & english speaking also . It is also possible to pay them monthly by direct debit charged to your credit card. ( still can't get BBC,ITV without the 2m dish though... try justin.tv ( free streaming site ) for any sporting events that BBC/ITV cover that Sky don't & then there are plenty of websites that you can download all the usual Sat. night BBC bubblegum for the brain light entertainment shows.)
