Downloading YahooGroups has become near impossible with 
HTTrack. Rick T informed me there are some specialized 
other programs that do only YahooGroups download and are 
better at it. Unfortunately they are not free like HTTrack 
but they cost around $15 so not too much. Anyway I'd like 
to pass on the information to you others:


<http://www.personalgroupware.com/>

and

<http://www.pgoffline.com/>

The last one makes it possible to share the download 
between more users to workaround Yahoos limits on how much 
you can download at one time (more than 300 messages 
downloaded blocks your IP address from yahoo access).
Also possible to export to Access database with the last, 
which could be useful if you wish to transfer archive to 
your own Content Management System at some stage.
