At first I hesitated joining this site but now i'm glad I did. I am happy to see you really do have thousands of downloads. I just downloaded the software I needed. The service is great. Thank you and Ciao!

I'm not sure why some people think this is a scam site because i've just downloaded many of my favorite TV shows! The members download area is well done. This was worth the few dollars it cost me!

Helpful Information: What is a Serial?
The word "serial" in warez context means a unique number which identifies the license of the software as being valid. All retail software uses a serial number or key of some form, and the installation often requires the user to enter a valid serial number to proceed. A serial can also be referred to as a "CD Key". When you search for "pdf 3.1 serial" for example, you may find the word "serial" amongst the results. This usually means your warez download includes a serial number.
