I don't know if it is just me or anyone else, but I can post a horse's link perfectly fine in chat, but in the forums it won't work. I have already tried clearing everything. I restarted my computer. It works fine on my phone, but the link posting won't work on my computer.

When you post a link hit "remove code" at the bottom to the right of the submit button.

Do I have to do that everytime?

If you're using Google Chrome, right-click and Paste as plain text. This won't have any coding attached to it. Otherwise you will need to use the Remove Code.
