Every league needs to run some form of basic content which Teams and Players need to be able to access. This could be your league rules, your league constitution, bylaws, about your committee, an FAQ page… Any number of different reasons.
RackEmApp provides a basic content management system to allow you to operate pages like this.
Use the rich text editor to format your text, upload imagery or even direct copy-paste to make it even easier.
Draft pages prior to publish using the Active identifier, and sequence the page so they appear in the right order in your league page.
