improve definition of 'presenter role' (CRO:0000100)

[StroemPhi]

Dear CRO team,

I'd like to suggest to improve the definition of 'presenter role' (CRO:0000100) from

Oral presentation intended to present information or teach people about a particular subject, such as a talk or poster presentation at a conference.

to

A contributor role that inheres in a person who speaks about a certain topic at a social event, either in form of presenting or teaching information to an audience.

And wouldn't it also make sense to add the subclassOf axioms:
ro:'role of' only ncibtaxon:'Homo sapiens'
bfo:'realized in' some obi:'planned process'
