Temporarily limiting the investment feature

For the time being, we will no longer accept bankroll investments from completely new investors. If you didn't invest into the bankroll in the past, you will thus be unable to make a new investment starting right now. Currently active investors are not affected by this change, everyone who's got a standing investment into one of the bankrolls right now will still be able to increase, decrease, or remove any of their investments. While this change is only temporarily, there is no fixed point at which everyone will be allowed to add new investments yet. We'll inform you once the restrictions are lifted.
