hey I'm not going to lie I'm new to this site and finding things slightly difficult to navigate around. I was briefly looking for ways to edit but couldn't find it so decided to just post again. Thanks though!
To edit a blog post hover over your name on the black bar and hit Manage Games. Pick the game you want to edit parts of, then pick what kind of thing you want to edit. There'll be a blog option, pick that and you'll be taken to a list of your blogs. Click edit on the one you want to change, and done! >.<)b
Also, if you want to, you can add media to a media page (you can pick what kind of media it is - including choices for LPs or gameplay videos, etc).
Lastly, if you want to embed a youtube video on the site, use the youtube tags with a link that is set up like this: https://www.youtube.com/watch?v=RxglJwcSA0g If it's not laid out like that (with the www.youtube.com and the watch?v=ID Number) then it won't work with the tags.
