As reported by Heroin, new guild members cannot join raids for 24 hours (by design), but they can create them. This is inconsistent, and arguably wasted turns.

Also, if the guild rank out of turns, it is possible to exploit the turns of freshly registered accounts, because they could be used to create raids immediately. This is the reasoning behind disabling raid creating for new guild members.

Also, if they don't know any better and create a raid and think they can join it, is a bit disappointing to them I'm sure. (Which is what happened)
