DON'T JOIN GROUPLY.
Grouply is a service where you can try to combine all your yahoo
groups for convenience. Problem is to do this you give them your yahoo
id and password so they can get access to everything in your groups.
this means an outside service can get access to all the post and
repost them elsewhere (a violation of yahoo terms of service) as well
as any posted email addresses. once this happens you can see where it
could be a spammers paradise with all this inside info...

Spammers have done this sort of thing in the past, but the problem
with this is its automated and very through to 'market to' yahoo group
folks, so, please do not join up with grouply or any group that will
want your yahoo userid and password as it then opens us all up on the
group to the outside source who will most likely do stuff with the data
that none of us want.

Thanks,
Group Owner
