[Air-L] software to download yahoo group data?

[Tery G]

Hi all,

I've been running a few similar yahoo groups for about 8 years now.
I'd like to download data from those groups so I can take a closer
look at them. I can find programs to grab the messages and photos, but
nothing that also grabs the moderator data -- when members joined and
left, etc. Does anyone know how I can get that data other than
copy/paste? I have both a Mac and a PC, so it doesn't matter what
platform the software runs on.

TIA,
Tery Griffin
