Remove Skype ads

1. Exit Skype
2. Open Internet Explorer
3. Open Internet Options
4. Go to Security and select Restricted sites
5. Click Sites
6. Add https://apps.skype.com/, click OK
7. Go to General, click Delete, and click Delete again
8. Open Skype, the blank space should be gone and there will be no ads

I don't know what the implications are and whether there any issues with other skype apps, but so far this is the only possible solution that I can think of."
