Imo.im offers one more feature that separates it from other websites that let you log into your instant messenger. The so called Group Chat feature lets you invite buddies from all four instant messengers that are currently supported. This way you can chat with everyone even if they do use a different instant messenger. Buddies do not have to sign into Imo.im to use the group chat feature. This would only be necessary if they wanted to invite other users by themselves.

I personally think that Imo.im is already a great alternative to Meebo, especially if Meebo has been banned from your network. This new service is surely to new to be banned as well which makes it an excellent opportunity to use instant messenger services. Imo.im is still a early alpha but already working fine in my opinion.

If you did try Imo.im let me know how you like the service.
