Skype Groups Edit
Skype has 2 types of groups, one is cloud group, which was first introduced in Skype 6.13. In Cloud groups, you can remove users, enable/disable group linking, and chat history when a user joins (if you're admin). Another type of groups, is P2P (Peer to Peer) groups, P2P groups have more features and is more secure, you can lock certain features to be admin only, ban users, and add users to a banlist, and much more. if using a version older than 6.13, only P2P groups are accessible.
Skype Commands Edit
Depending on which type of group you run on Skype, there are some commands exclusive to P2P.
|/me||places a massage in the centre of the Skype application with /me being replaced with the username of the user|
|/topic [text]||Changes the Conversation topic of the group the command is being done in, it is disabled in P2P groups that have the conversation topic locked.|
|/add [+Skypename]||Adds a user to the Group, to add a user to the group, type their skype id after the /add|
Microsoft acquisition Edit
On May 10 2011, Microsoft acquired Skype Communications, for $8.5 billion. The company was incorporated as a division of Microsoft, and Microsoft acquired all of the company's technologies with the purchase. This was completed on October 13 2011.  As a Result of this, versions of Skype eariler than 6.21 have been discontinued and made unable to be used to access Skype's servers. There have been patches made for older versions of Skype to be able continue access to Micrsoft's servers.
Skype Protocol Edit
Skype has a closed source protocol. Unlike most protocols (including Microsoft's MSNP, for Windows Live Massanger), its not as wide spread. Kopete supports Skype's Protocol (versions 1.0 and 2.0 only) and Pidgin's Skype4pidgin plugin also supports Skype's protocol. Microsoft's TOU says that "reverse engineering is not allowed" despite that most countries have laws that allow it.
- Before version 7, Skype used to have a slightly different layout, one of the notable changes with the layout was that before version 7, the avatars used to be square to fit the whole image into a box, version 7 changed the shape to circles.
- Skype also had additional changes made in later versions such as moving the menu buttons and changing the colours of the notifications.
- an emote in older Skype, the finger emote, was removed. But was added later.
- 2 Emoticons (poolparty and mooning) are censored in the later Windows versions, other versions have the emoticons uncensored.
