www.smstexter.com allows you to send text messages to any worldwide mobile phone network for free. SMS text messaging is both fun and fast growing, so keep in touch with your friends and family quickly and easily using our service.

There are plenty of free SMS providers on the internet today. But the problem with these providers is they allow you to use only 140 characters & fill remaining space with ads. It looks so unusual to put ads inside personal messages we are sending! SMSFame is the first website I know which allows users to send free 160 character SMSs. SMSFame relies on online advertising rather than placing ads inside SMS. SMSFame requirs a simple registration process before you start sending SMS.

I had a problem with Windows 7 where the Compressed File option was missing from the Send menu. Luckily I knew how to bring it back. This will work for Windows Vista also.
1. Hold down the Windows Key and press R or go to Start > Run.
2. Type regsvr32 %windir%/system32/zipfldr.dll
3. Click OK.
See if the Compress Folder option is back. If not you may have to perform these steps.
1. Open Notepad.
2. Click File > Save As…
3. Name the file Compressed (zipped) Folder.ZFSendToTarget and Save it.
Try that out.
