First, let me highlight the benefits of this particular service:
- both free edition (1 operator, 1 IM channel, 1 department) and commercial editions for advanced users (starting at $6/mo) are available.
- the chat does not slow down page load time. Actually, the script doesn't even start loading before chat is "activated";
- localization (interfaces in Russian, French, Spanish and more);
- cross-browser support;
- support for a wide range of IM protocols for chat operators (in my case -- for my travel agency representatives). This includes XMPP (jabber), ICQ, Yahoo.
Now let's proceed and try to implement this easy chat solution.
