Actually, very little writing is required. You're only required to set up a few items on your Leadership Page, including your Advisor greeting and your best tip for success.
Your greeting can be just a couple sentences (and feel free to use parts that you like from the LP sample page HERE: www.sfimg.com/Resources/Leadership?id=11439709). Likewise, your Best Tip can be very brief. Just state in plain language your best tip for your affiliates.
