In fact, I was kind of assuming that the backend just counts articles in a server, just like nnml now counts articles in a group. > In particular, if when I enter a large group and gnus asks me how many > articles, how would that article subset be chosen?

But nnml in principle has the same problem, so maybe a similar solution could be devised? However, I'm afraid it might boil down to keeping a list of numbers for each group, which is kinda like the first suggestion that you made that I rejected. Hm. Well, I think the Agent already keeps such lists, and it works in principle, so the amount of data involved is not too big. -- This line is not blank.
