*Putting on the serious hat again*

Yes, we do have coding guidelines.

Yes, I do see the need.

We are only 10 in our company.

IMHO, coding guidelines are needed even if you are a one man company/team. Once you define a standard naming convention and stuff, it gets easier to find stuff in your own code.

Problems arise when you put away your code for a couple of months and have to do some new work on it. If you stick to your guidelines, it will be easier to get back into it.

What should be in coding guidelines?

1. Naming convention (for variables and stuff)

2. Comment block for functions and files
