Look up top in your post area. At the far right is the icon for embed. If you click on that and choose the Twitter icon you'll get a popup window that says, "Embed Tweet." At the bottom of that window is something that reads, Show Twitter embed help, and when I clicked it, it totally didn't work for me.
Here's what worked for me. Go to Twitter, find a tweet. Click on that tweet to enlarge it and make it the feature window on your screen. Go to the URL bar up top of your browser and copy that address. Now, in your Depporgraphy forum post space, click on the Embed icon, bring up Embed Tweet, and paste the Tweet URL you just copied, into the text box. Click on Embed and you're set! You will see a placeholder in your post (click on Preview if you don't see anything) but after you finish your post it'll all show up perfectly.
Hey Bonnie, thanks!! I do it a slightly different way-- under the tweet, next to the heart there are three dots ( ... ) the logo for "more". If you click on that, the 2nd choice is "copy link to tweet" so you can just copy it that way, then follow the same instructions above.
Example (this is a screenshot to show the "More" menu, not an embedded tweet itself-- I don't know why it looks so much bigger than my own screen display ):
