Includes custom HTML/CSS/JS code in the network.
Very simple, but sometimes useful plugin.
After activation visit Network Admin --> Settings --> Multisite Ads for setup. Nothing else is needed.
Developed for private use, but has perspective for more extensive usage. I can't guarantee any support in the future nor further development, but it is to be expected. Kindly inform me about bugs, if you find any, or propose new features:
