 ## Protocol support

 - Circles/Groups for Windows Live Messenger 2009 are fully implemented, however, managing members is expected to be done from the CrossTalk website. You can use `script/managecircle.py` to perform a few actions on a Circle and its users (run `python script/managecircle.py -h` to see instructions)

+- Windows Live Messenger 2011/2012 supports authentication, viewing your contacts list, presence updates, and MsgrConfig, and instant messaging. Most other functionality is either unimplemented or untested. Peer-to-peer functionality (display picture syncing, file transfers, activites/games etc) currently does not interop between 2011/2012 and older versions; it only works with other 2011/2012 users.

 ### IRC
 
-IRC support is going to be completely reworked with the introduction of chatrooms, but as it stands, it's fairly basic. It offers the ability to create, join, invite people to, leave, and list other people in temporary chats, and to set your nickname, view the MOTD, and set an away message. It also requires `USER`-based login with your account credentials, however, IRC-only guest logins are planned.

 ### OSCAR (used by AOL Instant Messenger and ICQ 2000 - 8)
 
-OSCAR support is basic. Right now, only `FEEDBAG`, `BUDDY`, et cetera are partially implemented, and it supports showing your buddy list as well as presence updates. Messaging currently isn't supported yet. Only the FLAP authentication method and BUCP with the older hashing method (used by AIM 3.5 & 4.x) is implemented. It has been tested to work with AIM 4.3 and 4.8; older versions may be hit or miss. AIM 5.x - 7.x, TOC/TOC2, WebAPI, and ICQ are not supported yet, but support for them is planned and will come in the future.
+OSCAR is basic, but functional. Right now, messaging and buddy list management is implemented. The FLAP and BUCP authentication methods are implemented. AIM 1.0 - 5.9 are supported, but 4.x and 5.x are where most testing is done, so older versions may be hit or miss. AIM 6.x - 7.x, TOC/TOC2, WebAPI, and ICQ are not supported yet, but support for them is planned and will come in the future. Not sure about AIM 8 because of NINA getting exploded.
