If you have more than one Skype account – say one for business and another for personal use – you can run two Skype applications at the same time! Provided you have Skype version 4 or better. The following “tip” applies only to Windows, as I haven’t had a chance to play with solutions on the Mac.
Step 1: Go to the location to where you installed Skype. For example:
Step 2: Right-click on the Skype.exe icon and select “Send to” -> “Desktop (as shortcut)” to create a new shortcut to it on your Desktop.
Step 3: Now go to your Desktop and right-click on the newly created shortcut. Select “Properties”.
Step 4: Append the following to the “Target:” text field without changing the existing text:
Step 5: Select the “General” tab and give your shortcut a meaningful name like “Skype 2″.
Step 6: Press “OK” and then double-click both your regular Skype shortcut and the new one to start two instances of Skype.
Have fun and don’t forget to request “add me to your contacts” before making a call.
