Oh dear, the threads are continually spiralling.
Just to clarify;
SKYPE is a completely free program, if you have broadband you can use your microphone to speak direct to anyone else who also has SKYPE on their computer.
If you subscribe to their telephone service you can also use your phone and call anywhere in the UK completely free of charge, you have to be online to do so.
You top up credit online, charges are made for calling mobiles or abroad.
For about 3-5p per min you can call any land line in Europe. Or you can speak to friends or family for free if using your computer microphone and they are also online.
I'm locking this topic, interesting though it is, it has nothing to do with window cleaning.
