Here's a great substitute for a sign that allows you to write text!
Spawn a head, enlarge it. Then get out the "Cut" tool, then cut letters in the head! (That may sound wrong.)
But, here's a pic of what I did.

I hope that helps!
Here's some tips how to have fun with this game even more!
You can shoot a gun by holding it, & pressing "F".
You can spawn medical stuff, & drag it on the rag-doll.
If your rag-doll is bleeding, spawn a bandage, & smack that on his cut. (If it doesn't work, just try to make the bandage hit right where he's bleeding.)
This is really cool/fun. Search "Medgun", & press "F". & then search "Heal Grenade", & then press "F", too. Especially if/when your rag-doll's bleeding.
& look to the top right corner > Click on the last (4th down) thing with the purple-thing. You can click on powers > Click on one > Then click on your rag-doll.
Very fun game!
