create_post

Post an LFG on LFG Atlas FOR THE USER, only when they asked you to, using THEIR OWN contact (Discord invite, Discord username or in-game name). Never post on behalf of anyone else or copy other people's messages. Same rules as the website: no links in text, no trade/scam ads, 1 post per 15 seconds and 10 live posts per contact, plus generous rate limits; an exact duplicate of a live post returns the existing post (duplicate:true). Returns the post link and PRIVATE manage links to give only to the user.
