Solutions Should Now Be Saved in .Docx Format Only

Hey everyone: This week's tip is a big one, as it will be going standard in the next revision of the guidelines:

Please save all files as .docx. Simple as that.

Luckily, this update will probably save you a step, since you can now save all files as .docx rather than converting to .doc.

Please make sure you use only this file extension for all files going forward!
