As of Discipline version 2.1.0, signs are supported. To make a heal or feed sign, simply type [Heal] or [Feed] in the first line of the sign. For a teleport sign, type [Teleport] on the first line, the desired X co-ordinate on the second line, the Y on the third, and the Z on the fourth.
To use a sign, just make sure you have the correct permissions, and right click it. By default, only ops can place signs, and everyone can use them.
