Forum:Chaining

Based on what I read in the wiki, Continuous Effect Monsters do not start a chain and it can't be chained to it. Continuous Trap Cards can be chained and chained to. What is it for Continuous Spell Cards? If it doesn't start a chain, can it be chained to (since it is not a monster)? I ask because of one of the rulings for Ectoplasmer. 24.106.177.50
