Clerky beats 83(b) into the heads of founders who use its service. It's included in the package, with pre-filled forms and detailed instructions for where to mail them, and it sends you nag mail every week until you've uploaded the completed IRS form. It works for employees, too, but they don't get the nag-mail.

The folks who I think really need to teach their employees about 83(b)s are fast-growing big companies. I didn't know about them when I joined Google, for example, and learned about it too late to take advantage of it. That mistake cost me literally hundreds of thousands of dollars.
