Do you know if there's anywhere to call for people to see if they're a member of restricted groups with inactive moderators? I've applied to join several, just in case, but chances are good that the mods don't even check that email anymore and will never approve the membership. However, some of those have several hundred members and there's a chance that one of them might see the notice if there were a central place to link to with a post that people could send out, kind of "if you are a member of one of the following groups, please contact us right away to help with archival!" that sort of thing. I can handle joining any public group and grabbing all the messages (I haven't even been following the message restrictions recommended by the program, but haven't had a single lockout from Yahoo so far despite grabbing two 50+k archives straight…), but the private ones where the mods have abandoned them, those seem to be lost causes. :(
