After some talking on IRC with a few of the folk, I thought this may be a good idea for a sticky thread, even though this place is getting a little cluttered with them. We see a lot of the same question day in and day out that require a simple answer and do not require a whole thread for them.
Example: "What happened to my transform gizmo in 3dsmax?"
This thread will be a collected list of these things. Please, only post a question if you can post the answer in the same post. Add any questions that you get asked by people new to the 3D field regularly.
