Makermod
Makermod is a modification by Scooper for multi player, originally started by Toast. It is similar to Lugormod, however everyone is allowed to build and cheats are enabled on most servers. Its capabilities are also more limited than Lugormod's.
In August 2010 Didz became a coder for the Makermod clientside and somewhere in 2012, a full Makermod developer.
Building
Players are able to load models from the game to be able to place them on a selected map. With crafting skills and little imagination constructing pretty much anything is possible with the available commands given.
