i think if i have members with my site, a chat room would be helpful to keep them sticky. what do you think about it? i found a chat application with a flash client, it is a good choice? here is a live demo of it, it worths you a try also, i think. www.123flashchat.com/demopage_2.html
thanks for your reply. i checked the site the Tufat. There even is no screenshot of the chat. And the license fee is just $5. Seems it is a self-written application by a programmer? 123 Flash Chat costs a little money. But it comes from a big company, so it looks more reliable. here is a monthly promotion of it: www.123flashchat.com/promotion_2.html
With a chat room, why would your members need to post in your forum? I have found that my forum makes my chat members sticky, lol.
Could you give us more information about what your site is about? It could really depend on what service your providing, it may be useful or unnecessary.
A chat only helps if there's people connected at all time. You need a lot of traffic to make it worthwhile.
