What Nigel said. For anyone unfamiliar with cut and paste method, here’s a full description.
Cut (actually Copy). You can’t simply select all (ctrl-a) because that captures everything, like buttons, banners, and the unwanted right panel listing “Latest Replies”. Instead use the mouse to select what’s wanted.
Go to the bottom of each page, and position the cursor by left clicking the mouse on the far right end of the last post. With the left button held down, drag the cursor all way up to the far left of the first post and release. The selection will highlight as you go, confirming the mouse picked what you want. The page will scroll as necessary.
At the top hold the right button down, and select copy from the pop-up menu.
Paste. Start Word, or other word-processor, and open a new document. Position the cursor at the top and select Paste with the right-mouse button. All being well, posts copied from the forum will appear in Word, and can be word processed in the usual way.
Repeat for each page of replies.
Same method allows single posts, or parts of posts to be copied.
Gotchas! The computer may not let the user Cut and Paste with a mouse from a website. Done to block a type of hacking attack. If so, Copy and Paste are done with the keyboard: Copy is Ctrl-C and Paste is Ctrl-V. Selecting is still done with the mouse.
