CHAT BOXES TO EMBED INTO YOUR WEB PAGE

SUMMARY
I do not know how to make Yahoo Pingbox visible to all visitors.
Meebome is easy for visitors, and can be used on multiple sites
Digsby is not the easiest chat box for visitors
Hard to use on multiple sites without a subscription
Problems for visitors to the website containing the gadget
Requires the visitor to have previously visited the Yahoo website, and not deleted cookies since.
Otherwise, the visitor sees a white square where the Pingbox should be!

No initial "Type ... here..." message, making it hard for visitors new to Digsby to know where to type their message
Displays an advertisement, which makes the box slow to appear.
Zooming out, E.g. by Ctrl+- can cut off the text entry box


The online...
"Type your message here"
entry box is the second of four, and therefore not as obvious as it could be.




The entry bvox background is grey, making it harder for the visitor to identify the box and see what he is typing.
Size of text seen by visitor
10pt, but does not increase size as the browser is zoomed in
10pt, but does not increase size as the browser is zoomed in 10pt, but does not increase size as the browser is zoomed in
Font of text seen by visitor
Compact
Compact Spaced out, but I think less, rather than more readable

Response to changes in Chat Client
Switches between "Available" and "Busy"
Switches when the visitor refreshes the page only
Status switches between  "... is online" and "... is away" , and lists any new status message

After page has not been refreshed for a while, visitor sees..
Says "Your session has been disconnected because messages have not been sent or received in the past few minutes."
Continues to say ".. is offline/leave a message"
Says "Connection failed" or the last status message  whether Digsby is running or not.

and when he invokes his Chat Client, the owner sees..
The stale web page  is not listed as a visitor Stale pages remain listed, but the listing dissapears a minute or so after the page is closed
The stale web page  is not visible in Contact List
Multiple chat
Yes. widgets are named, and listed in alphabetic order. Each visitor generates an entry under that widget Name
Yes. meebo me widgets are named, and appear in the user's Contact List in alphabetic order. Each visitor then generates a new "meeboguest number". whenever a visitor refreshes the page, the meeboguest number is bolded for 3 seconds.

Not with the Free edition. You can chat to 5 people if you upgrade at e6.99/month.

Installation

How invoked by the owner

Worked with Windows Live Messenger a couple of years ago, but now WLM says Offline, and does not communicate.
Key generation worked in the past but now gives...
"This WIMZI is missing the appKey parameter so it will not work.  Please use the sample code from http://wimzi.aim.com."
