I agree with James and support his proposal. I would also support editing the existing pair to show 'tautologous' as [form.] and 'doppelt gemoppelt' as [coll.], or something along those lines.
Technically, if I understand correctly, there may be a slight difference in that 'redundant' more properly refers only to the second (unnecessary) word, whereas 'tautologous' refers to the entire phrase or sentence containing two words, the second of which is unnecessary. But in practice, 'redundant' is certainly the word most people use for the whole concept of 'doppelt gemoppelt.'
While we're at it, I might also suggest marking the 'arbeitslos' sense of 'redundant' as BE. As I understand it, AE 'to lay so. off' is roughly the same as BE 'to make so. redundant' (i.e., AE 'laid off' = BE 'redundant.')
@James: Be patient, okay? After all, it's a holiday week. (-:
Thanks for that helpful summary, with which I largely agree. (-: Just one question, though.
>>since, in a certain sense, a change or addition to an existing entry suggests an incompleteness on its part, such suggestions should also be in Wrong Entry.
Doris will correct me if I'm wrong, but actually, that's not how I've understood the system so far. Of course practice tends to vary, and fortunately the LEO team is relatively easygoing and not too obsessive about nagging people to use the 'right' forum. And especially Doris is usually very kind about going ahead and handling suggestions without too much fuss regardless of where they appear, especially if they're from new users or sort of in a gray area between New and Wrong. But in general, I thought Wrong Entry was intended primarily for word pairs that need to be removed or edited, and perhaps very occasionally for closely related suggestions that are easier to handle as part of the same decision and research process.
In any case, James is quite right to point out that there's no central, easily visible explanation of things like when to use which forum, and that several aspects of the forums can be confusing, especially when one happens to enter from a page other than the forum homepage. And although I understand that the LEO team is short of people, time, and resources, and I sympathize with their frustration and very much appreciate all their efforts, I'm afraid I do have to agree with James and others that the practice of putting up supposedly 'temporary' error messages is not a very helpful way of handling features that no longer work at all, such as the full text search (archive & forum both) and the Resume Discussion feature.
Fortunately, most new LEO users are probably not new to netiquette, so they usually realize that it behooves them to lurk for a few days (or even weeks) to get a feel for accepted practice in a new forum. However, there are evidently also a fair number like James who find the lack of explicit help frustrating -- not to mention the probably larger number who don't take the time to ask or comment but just leave, probably never to return.
Again, I'd be happy to help draft a forum FAQ if that would be of any use. (-:
