I improve LimeSurvey core freely, some of my plugin are made freely. But right : here it's a really big part.
We know that it is not the money for you. But I also understand that certain things need some funding. At the end of the day, even a Denis needs to eat and can't just live of OSS coding, air and love.
I answer at the LimeSurvey forum in my spare time, I'm not a LimeSurvey GmbH employee.
