What music are you currently listening to? - Page 474 - PentaxForums.com
I tried to enter a YouTube link, which normally embeds the video into the post. This time, it glitched and added a bunch of code like text into the post. When I went to edit it back to only the link, it left the link as text only, not even auto-formatting as a hyperlink. I finally tried to add the url tags to both ends, but the forum changed the [/url] tag at the end to [/ame]. I thought maybe I made a typo, so tried to re-edit and it happened again, and then a third or fourth time. For now, I left it as plain text.
If anyone knows what is going on and can fix it, it would be appreciated.
