I got a same WhatsApp message from a number of friends. The message is about WhatsApp will charge for their service unless you are a frequent user. And it asks you to forward that message to 10 people. I checked the official blog of WhatsApp. That is not truth, the message is a hoax. If you get that message, please do not forward that!!!

There are a number of ways to create a pdf file by using open source software. For example, openoffice can export their document files into PDF. But How's about others file type? For example, how can I export a web page into PDF?
I found the best way is getting a PDF Printer driver. I just need to open the file and print it into a PDF Printer. Then it will "print" into a pdf file. I am using PDFCreator to do this task. It is free and opensource.

I found some friends who are not in MSN for years. But yesterday, they suddenly came online again! They are always online too! Moreover, their MSN photo changed to a sexy girl. They will send me a "Happy Holidays" message too! Then they will send another message asking about dating. I know those friends well, these should be their actions. I think their accounts hacked. Be aware!
