Is it acceptable to post a link to my YouTube channel with an introductory video promoting my game here on Roll20? The guidelines posted to the LFG listing forbid external links, but this would be for a game hosted solely here, I just would like to show any potential players some of the content of the game they might be getting into with custom videos. I'm just not sure if that would result in a deleted post or not, it seems to be a grey area.
