I recently asked about how to make the short links to other threads. jbriggs44 showed me this: [URL=https://www.physicsforums.com/help/bb-codes]like this[/URL][/QUOTE] Then Drakkith said "Highlight the text in your post you want to make into a link, and then click on the icon that looks like a chain." I don't see any chain icons. The only icon I see is the large sigma (to insert symbols). Oddly, when I use that, it inserts the selected symbol at the very start of my reply/post (it doesn't insert at the cursor location). Why can't I see all of the tool icons? Internet Explorer 11, on a computer at work. Thanks!
