First of all, Wei and Kyle thank you for your answers.
@Kyle I see the point about the grammar being unambiguous due to its parsing and the direct mapping between phonemes and graphemes also taking pronunciation ambiguity out. Nonetheless I refer to other aspects of the language or even the grammar itself in the sense of knowing how the different components were decided to stay like that. For example any sounds could have been selected to be the phonemes arbitrarily, before creating a nonambigous mapping to graphemes, or this phonemes could have been selected to maximize their auditory discrimination based on some sound variable or something like that. Also for example the grammar rules themselves must have a history due to loglan, but I just wondered if you could point me to some easy guide on the evolution of the grammatical rules selected.
In general I mean some material or maybe a person to contact that could introduce me to the path of creation of the language and not just to its final state.
It would be really nice if we could discuss this by voice/chat, thank you again for your guidance.
