This is from yahoo. Please let me know how this group is going to
handle anyone who is a member or joins with a grouply email address.
Grouply is the most popular 3rd party website at the moment there are
others also.


If you are considering providing your Y! username and password to a
3rd party site which stores that information on their own site,
please carefully consider the risks before doing so. Giving access to
a 3rd party can be very unsafe as the 3rd party site can access your
Yahoo account as if it was you accessing your own account. For
example, they could access your address book and send emails to your
friends, change your account settings, or gain access to your
personal information. Under Section 5 of the Yahoo! Terms of
Service "You are responsible for maintaining the confidentiality of
the password and account and are fully responsible for all activities
that occur under your password or account." For more information
please also refer to section 5 of Yahoo's Terms of Service.
Group Moderators have the responsibility and the right to enforce
their own membership guidelines for their group. The guidelines can
relate to how group members deal with or interact with 3rd party
websites. If a member is part of a 3rd party website in which the
site accesses the group content using the member's login information
and/or the user's email and then makes this content available to
other users, this behavior could put them at risk of having their
membership to the group revoked by the moderator or for having their
Yahoo! account closed entirely for a TOS violation. Moderators have
the right to protect their group's content along with the privacy of
their members and can and should enforce this at their individual
group level. For more information, please refer to section 11 of the
Groups Guidelines, section 12 of Yahoo's Terms of Service and
privacy/security information.
Groups owners and moderators should take every opportunity to protect
their group members' privacy and integrity of the Groups community
and as such, Yahoo's Terms of Service and Groups Guidelines should be
referred to when dealing with all situations including 3rd party
websites.

Thank you,
Groups Team
