Advanced Topics are just that - advanced.
What is advanced? For our purposes we feel the CMS is for MANAGING content but we create sites in it and so if you know how to code CSS and understand HTML for the most part you could potentially tackle an advanced feature. If not you risk breaking something and it would be in your best interest to leave these issues to the professionals.
Some topics have features we really don't expect customers to ever mess with and so we will gloss over those. Often though OWT might set something up initially but you might need to modify it a bit over time. No matter what these features are going to be minimally documented so if you need any help please contact us.
