I'm on 3.2.0. I just want to add a couple of special characters to be available when people are posting, specifically a check mark to say yes that's correct, and a red X to say that's wrong. So I found the images, sized them and uploaded them into my mywebsite/phpBB/images folder, and then I went to ACP/Posting/BBCodes, and I hit "Add a new BBCode" and put a link to the image in the BBCode Usage box and hit submit.
So then I get the information/error message "the BBCode tag name you selected already exists." Does that mean the check character I want already exists, or my coding is off, or I'm putting it in wrong, or what? I just have two special characters I want to add. I've been told they're already in some kind of set in 3.2.0 but I can't find them, so I thought I would just link to .jpgs I sized and prepared and click on "display on posting page" and I'd be done.
