As Peter already mentioned, you can set Validate=All and people won't be able to do *anything* by themselves. That should do what you intended (and perhaps a bit more?). If you only want to trap some subset of the list, then you could setup two lists and have one list subscribed to the other. Put Validate=All on the list where you want people permanently subscribed, and leave that keyword out of the header of the other list. So long as people only post to one of the lists (you could play with Send=Editor to enforce this if you like) then it will work fine. If you wanted people to be able to post to either, you could make the two lists peers. -jj PS - The only problem with having two lists is that they both have to keep archives if you want people to be able to receive "digest" or "index" subscriptions. So you'd end up with duplicated log files. If you can put all the "digest/index" subscribers on one list then you could still only keep one set of archives.
