A couple of days ago I received an email from a researcher who is currently completing her PhD thesis and asked me to provide some information on Solresol.
Here is the link, the poll is quite serious and academic:

She asked me to share this with you and I strongly encourage everyone who is interested in Solresol to complete this survey, this will help us to spread the word about the language to mainstream linguists.
