Our single DNN portal supports all of our customer companies (100s) and uses significant amounts of custom code. Each company has a company-ID that when assigned to a DNN user profile allows that user to see all the sites, buildings and meeting rooms owned by that company (but obviously not information from other companies). We had planned to write our own room and event scheduler when we saw your product and our lead developer thinks we could possibly save time and money if we integrate your product into our service instead of reinventing the wheel. However, you are set up for a single company so we would need to have a method of displaying the proper information for the user's company. Currently the user has a tree view that shows all resources for their company and the tree selection returns the specific resource-ID. Using your source can our schema be compatible with your product?
Thanks

If I understand your requirements correctly, you can have a cross linking for the user and company, then events with multiple company in a separate table, so in this case, you also build up a one event multiple company relationship.

My answer is, yes. you can customize it using the source codes but you may need to study a little more to find the best way to integrate it to your site.

Try get a copy and test it on your site maybe good to start with...
