I'm looking at a really large binary group and, being it's so big, I have to download the headers in thirds or else I run out of RAM (I've got 3GB too!) I'm used to using xnews as my windows newreader and that program allows me to pick where I begin downloading the headers. Thus I can cancel my headers download one thrid of the way through, then look through it, then start up at my previous stopping point to begin downloading the second third. I really hope that Unison allows something like this as well but I've yet to find it. The only options I see are get more posts, get latest posts, and get all posts. Anyone who uses Unison know anything about this?
