"Forms to Riches"
"WFFM is dead. Long live Forms. One of the most popular Sitecore modules has finally been given a modern overhaul. Moving from a mature module presents both great opportunity but also new challenges trying to replicate well established business processes. What the new Experience Forms means to you and how to customise it to fit your needs."
"SOLR Spatial Search with Sitecore 9"
"Have you ever had the need to search for list of places that were within a certain radius of a center point? Typically, you had to roll your own complex code, which would take time, or use a Sitecore Marketplace module that would help you achieve this functionality. However, with Sitecore 9 & SOLR you can achieve this functionality within a few hours. See how spatial search can aid search results for your organization, and how to take advantage of this functionality when using SOLR with Sitecore 9."
