It seems that lycos chat is indeed closing on the 1st only to become Noesis chat !
We are delighted to inform you that we have successfully reached an agreement with Noesis Systems Ltd. for continuation of the existing chat service.
You may have heard that our parent company LYCOS Europe N.V. has decided to discontinue many of its services.
The Chat business is one of the services which are scheduled to be discontinued by LYCOS. For this reason we will be terminating your LYCOS Chat contract on 1.3.2009.
Should you wish to continue using the existing product with the new provider, you will be asked to sign new Terms and Conditions when you sign on the chat.
As part of this agreement, your existing chatname and account content, for example your Logbook Messages and photos will remain.
Should you not accept the Terms and Conditions for the new provider by 1.3.2009, we will close your account and delete all of the content and access rights stored in connection with your Chat account, based on the statutory specifications.

So it seems users are going to have to accept new terms and conditions, it doesnt say if the urls are going to change though, as the urls all point to yahoo chat, it should be interesting to see what happens on the 1st of Feb.
