Obligatory means "required by a legal, moral, or other rule; compulsory". Reading your explanation (thanks for that!) it seems optional, not required. Is that correct? Cheers
Ah yes, sorry for the confusion; I've recently changed the requirements to some of my packs, making the link optional rather than obligatory. I must have missed this one in the process. Thank you for pointing this out, I'll go in and correct the text :)
