I would like to reference a website article at Point-Counterpoint: Additive vs Subtractive Rapid Prototyping that is a discussion between two individuals and posted by a third. I'm using Harvard British Standard referencing and it's not clear how exactly I should approach this situation.
In my references section, do I need a single reference crediting the poster, a single reference crediting both individuals in the discussion or separate references crediting each individual in the discussion? At the moment, I'm using the first option but I don't feel that it's correct.
It may be that an answer to this is a matter of opinion, rather than going by hard and fast rules, but I'd be extremely grateful for any help or advice with this issue!
