The City of Denton is currently working on a way to have all "educational" classes (rain barrel making, Sustainability 101, xeriscape, etc) that the City offers combined onto one calendar located on our website. This will allow for a central hub for these particular types of classes, offered by City Departments. As for the opportunities that other companies have available, the City cannot promote one company or organization over another. This can make it a little tricky when trying to combine and advertise some of these other classes or educational workshops. We are currently researching it further to see what can be done. Thanks again for the great idea, and stay tuned for additional information!
