Yes. it's possible.
Before you the web messenger link to your page, you need to let Cute Web Messenger get the information about your membership database.
CuteChat was built with the idea of extensibility in mind. Developers can easily integrate CuteChat with any membership database (e.g. portal or forums database). So users can chat with their existing screen names and profiles. No need to recreate everything you already have in place.
To help you quickly use the CuteChat in your ASP.NET applications, CuteSoft team has finished the integrations for Cute Chat standalone, DotNetNuke, Community Server, Snitz Forum(ASP), Rainbow Portal, IbuySpy and Community Starter Kit.
If your portal is not based on the above projects, CuteChat easy integration feature offer you an interface to allow users auto-login chat room without entering username and password again once they've logged in your portal or forum.
