Accounts with less than 5 posts can't post links, so... If they were trying to quote someone, the system might stop them because it has a link in the post.
For making new threads, they just need to wait 24h since the account's creation~
@Westeller I usually think that I might end up confusing people if I explain that they can make the thread 30min after their first post, or 24h after making the acc, so I prefer just saying the 24h one.
