Google Sheets beat Microsoft to the punch and introduced a Checkbox as one of the Data Validation options. You can go to Insert > Checkbox to quickly create one, and you can customize it by going to Data > Data Validation. I've updated most of the Google Sheets versions of my checklists to use that feature. I hope Excel gets smart and introduces a similar feature some day.
Now that you’ve created your site and have taken into account the feedback of your first set of members, it’s time to start promoting to a wider audience. We’ve published lots of useful content covering this topic, including some simple SEO strategies for membership sites, as well as a guide to creating a buzz around your program.  Then there’s social media marketing to consider, not to mention starting a blog to attract more of your target audience.

Again, unless your research makes it clear that your audience is ready and waiting to join your program, don’t produce your entire membership program just yet. Starting small and creating just enough top-quality content to keep charter members happy, then seeking their feedback before moving on to the next stage of production will help save you both time and effort in the long run.
Realize a couple of key facts: A) the prices for e-commerce software have fallen, so you don’t need to spend a fortune unless your needs are complicated, and B) many of today’s e-commerce packages include a full range of tools in one package, from an inventory management system to marketing tools. Many of today’s merchants prefer this “all-in-one” approach because it makes life simpler.

Checklists have been used in healthcare practice to ensure that clinical practice guidelines are followed. An example is the WHO Surgical Safety Checklist developed for the World Health Organization and found to have a large effect on improving patient safety[2] and subsequently found to have a nil effect in a cohort of hospitals in the Province of Ontario in Canada.[3] According to a meta-analysis after introduction of the checklist mortality dropped by 23% and all complications by 40%, higher-quality studies are required to make the meta-analysis more robust.[4] However, checklist use in healthcare has not always met with success and the transferability between settings has been questioned.[5] In the UK, a study on the implementation of a checklist for provision of medical care to elderly patients admitting to hospital found that the checklist highlighted limitations with frailty assessment in acute care and motivated teams to review routine practices, but that work is needed to understand whether and how checklists can be embedded in complex multidisciplinary care.[6]
