It is possible that the embed problem's from youtube updating something while the forum is trying to work with how it used to be, but I wouldn't really know.
I keep hearing of this supposed SC 2.0, so who knows what to expect further along. She does check on the place every so often.
I'm shit when it comes to PHP and languages like it currently, keep meaning to brush up on it. Even with that I can't say I'd make a place better than this, and I definitely can't say I'd be paying for it out of my own pocket when my work situations haven't really been the most lucrative.

Alright, I've found the problem that's been going on here with video links. This forum's code refuses to play youtube videos with "https" for some reason, but will play ones with "http". Source links on Youtube work because they give "http" while the embed source code has "https" instead. Embed code and embed links will work perfectly fine if you yourself delete the "s" from the link within it:

As seen in this topic, embedding video seems to be acting funny on the forum now. If you put in embed code it doesn't work properly, but if you put in the youtube video's link into the source itself it'll still post.
