Only been playing Eve for a few days and decided to check this out. Figured I'd use the 2 hour trial version to see how Deliverer works. Nope. Never got it to work and there are no updated tutorials I could find to use it.

Deliverer is old free addon to miner. It used to transport crystals/drones between stations for miner. Miners had no orehold yet and had to waste cargohold space. Newer version of deliverer is collector. You select central station and bot collect all staff within some range to this station. In deliverer you have to fill the table to transport each item you need (starting from longest name to shortest). Collector can transport all items.

I never tried to make deliverer better, it was developed for particular task
