I set FF to allow the pop-up, and then got a blank window (not sure if this is a problem with the site or with FF). I closed the window, and clicked on the chat link again, at which point I did get a pop-up asking me to login or register. At this point, I just gave up.
I would strongly recommend not requiring registration for this type of application.
thanks for comments about registration. I have the idea of allowing users to discriminate by nicknames. By Openid and Oauth users are already using the same id's on many websites, so i believe it would be ideal to use same ids on visitrs, for it's aim is to connect the websites community online in almost realtime. But maybe i'm wrong :)
thanks
Thanks for feedback.
Visitrs enables chatting in the same window regardless of whichever different domain the user is coming from, which serves the purpose "not interrupting the surfing process while chatting or vice versa" well (i guess :). In other implementations like using floating page elements or iframes for chatting, when user moves away from the domain,or opens another link in the same window, chat is interrupted.
I've updated the popup window contents where if popup is blocked, visitor can continue by simple clicking the inner link of the popup. I hope this will help usability.
Thanks for feedback.
