Just a thank-you for implementing this feature, now at the foot of every page of a thread. It makes archiving a thread FAR easier. For those who haven't seen what it does, give it a try.
You can, as well as printing the topic, save the results as either a text file or an HTML file. It displays IMG-tag graphics, and smilies that are part of the text, but not Webpage function icons or avatars.
It puts the WHOLE topic posted thus far on one Webpage, no matter what page of the topic you choose it from. And that's true even for all of a topic such as "SHAKES" Archive 1, for I tried it. It took about 5 or 6 minutes to load all those thousands of messages, but UBB did it. (I wanted to see if my browser would crash with so much text in one window. You need to know those limits.)
