Users integration and single sign-on are possible with 123WebMessenger, which means users of your website don't have to register or login again to access the IM.

Most of the popular CMSes can be integrated, Joomla, WordPress, vBulletin, DotNetNuke, etc., and there are still more to come!

License buyer or yearly hosting buyer get free integration service, while the monthly hosting buyer can pay extra fee to get it done, $100 per hour and usually we charge 2 hours or more, it depends.

The integration will be completed in 72 hours (skipping over weekends) because it's rather complicated.
