Hello,

As you can see from the headers below, 3 members from the French Arbcom, including an administrator of the list, have been removed automatically from the list. This seems to be due to the fact their email account is at Yahoo. We never had the problem before. What do you advise us to do ?
Thanks in advance,
Racconish
