mDiyo fails at OreDictionary registration. Don't worry about this (and don't expect Greg to do anything about it either).
I was about to say that. There is even a prefix for sticks (aka Rods), and his Rods would even fulfill all the requirements for the usage of said prefix, as those Rods are made of half an Ingot. (My Information could be outdated, but I think it is still 50% of an Ingot to make a TConstruct Rod).
Crafting Tables (made out of Natura woods)
For that I actually don't have a real Convention. I would have just made a crafting Recipe, which crafts the colorful Workbenches into a regular vanilla one.
People start to register random Stuff at the OreDict without any flags or markers, what these Items are supposed to be. If it is just for the sense of using the OreDict Crafting Handler, then one could register it as "insertmodnamehere:insertitemnamehere" or one could choose a prefix, which is definetly not a Name of one of those random Items out there.
