Robanan, even if I could make this available (I don't know of a phpBB mod to do it), I don't agree it should be allowed. If I allow this for you, other people will also have their reasons and want the permission, too. They are going to download too much stuff that they don't need, wasting bandwidth traffic. This is my opinion, though. You can ask the other administrators.
Now, don't get me wrong, I do know that not having a topic offline can be limiting because so far there hasn't been an easy way to search a single topic spanning multiple topic pages. That is why, as a consolation prize

to you and everyone else, I've added a very good phpBB mod to display a search topic box. I hope that this will help you handle individual topics much better -- after all, why would you download a particular topic, except for easier searching? I cannot off the top of my mind think of any other reason to want to download a multitude of individual topics. If you still really need a few topics to download, you can always use your browser's Save page function to download the page or pages belonging to a topic.
That said, could you please try the new topic search and tell me if that is better for you?
