You can't delete threads yourself. You can, however, ask the forum's moderator (in this case, LadyG) to delete the thread for you. You can do that by either PMing the Mod with the link or clicking the 'Report' icon on the first post (it's an exclamation point) with a request to delete your thread. For a thread like this, it's best to save the Mod the trouble by just letting it drop off the page and forgetting about it, though.
If that's really you in the pic in your other thread, you're a cutie. Edit to add some detail and personality to your post, and you just might get some bites.
