Awesome, you actually answered all the questions I had bubbling away in my head but didn't want to be too presumptive in asking. More decades ago than I care admit, I did a 25 hour Latin course. Very little of it stuck with me but it seems like Esperanto could fill a similar niche to the one I was trying to fill by learning latin, as a bridging language to be more capable in the Romance languages. I'm sure there are studies out there on language as sociology, as the largest con-lan I am aware of I wonder how deep that research runs? Another thing for me to read up on I guess.
Thanks again!
