[INFO] AIM support temporarily removed from GChat

We are temporarily suspending AIM functionality for our Chat product while we wait for needed system updates on the part of of AIM's creator, AOL. During this period, you won't be able to invite your AIM buddies to join your Chat list, nor will you be able to chat with the AIM buddies that you had on your Chat list. We apologize for any inconveniences caused by the temporary suspension of this feature.
We are in direct communication with AOL and they have informed as that they are actively working on these needed updates. Once AOL has finished updating their system, we will reinstate AIM functionality for our Chat product. We appreciate your patience in the interim.
