The nickname of the founder of DALnet is dalvenjah. Back when DALnet was founded the people who used to go there used to say "Let's go over to dal's net" and soon enough it became known as DALnet (officially suggested by MirclMax). The correct way to type DALnet is always DALnet, not dalnet,, DalNet or other variations.

There is a document which further describes DALnet's creation and growth, aswell as interviews with the network's founders in this document.
