Obviously you're talking about the yahoo group rather than this forum - they are two different, independent, and complimentary things. There are great people on both many of whom are members of both.
It sounds like you have some duplicate ownership of the lotuseuropa yahoo group. I don't know how that happens but if you go to the group site (
https://groups.yahoo.com/neo/groups/lotuseuropa/info), click on "Manage My Groups" on the left side of the page. You might see two entries for lotuseuropa where one is set up for a daily digest and the other is set up for individual emails. Set them both to daily digest. If that's not the problem, I'm at a complete loss. You could set up a rule in your email client to automatically delete the individual emails since the digest should give you everything you need.
You should also know about the Knowledge Base. You can access it from this forum on the main page towards the bottom or you can access it directly at
http://www.lotus-europa.com/ekb.html. That is a searchable interface to the posts on the lotuseuropa yahoo group. The rest of the lotus-europa.com site has a lot of great information (some of which is also available from the main page of this forum, too. The Knowledge Base reduces the need for saving emails and daily digests from the yahoo group. I still save some if there is a subject discussed that I have a particular interest in though, but it is somewhat redundant. One think to note is that the Knowledge Base will not have the very latest posts as it takes some time for the administrator of lotus-europa.com to load them up (however he does that!).
Let us know if that helps!
