How many spotlights can be added to your platform?
There is not a limit to the number of spotlights you can have in the left hand navigation of your site. The limit of how many can be shown on your homepage ass banners is three. I typically recommend having no more than 5 active spotlights as that is round-about what can fit on the left hand navigation without causing a volunteer to scroll.
When you're building out elements of your site, keeping in mind how a volunteer will experience every step is important. To me, the goal is to both intrigue and guide volunteers, so keeping things simple & fresh is key! A simple, clean, and visually pleasing site is a great goal to shoot for when thinking about what to put on your site.
