You should be able to edit the page in the admin panel without having to put it on the sidebar. Goto Presentation -> Theme editor and then you can edit your page.php to edi the code, or you can goto Manage -> pages and edit your page in there.
Not sure why moving it to the sidebar would make a difference
Oh, boy, this is complicated. To add information from another file onto your page, you can use the tag <iframe> but there are complications. If you put a Page into an iframe EVERYTHING in the page comes into the iframe, which means the sidebar, the header, the footer, and EVERYTHING thing you see when you click on that page goes into the iframe. Stuck in your sidebar, which is narrow, you’d see mostly white space if you are using the default theme of WordPress.
What you can do is create an html file that will hold the information you want, clean and nice with no header, footer, sidebar or other pretties to get in the way, and then link the iframe to that.
Iframes are brilliant pieces of code, but you should know that search engines tend to ignore them, they bork in different browsers depending upon their design and content,…and they just can be fussy and trouble…not always but sometimes.
I recommend that if you want to include a list of what you are listening to or reading, you check out one of the many plugins that make this an automatic process, easy to do, at http://www.wp-plugins.net.
Hey, thanks for the replies. Anyone know of any names of hacks which will let me add something like this to the sidebar? Having a look through the website now to see if I can find any.
