Repetitive pointless popups

At least they don't cover half the screen like the annual fund drive thingie I've repeatedly complained about, but as soon as i approach hymnary.org a little popup asks if I have a minute or two to give feedback about your sister site, what is it, Praise and Worship dot org? The first time it happened, I ran through the questionnaire, leaving a lot of blank spaces because I'm not really either a pastor or a worship planner or a worship leader in the usual senses. I'm a hymnologist, which is why I'm at hymnary.org.so often. But I have occasionally looked at (consulted might be too strong a term) your sister site, so I thought I might be able to help. But I doubt if it was much help. But ever since, every time I come here, that popup reappears, offering only a Yes or No option. Neither really applies, since "Already did it" is not the same as Yes or No. But "Already did it" is not an option, and even if it were I have my doubts whether that would make the little intrusion cease fire. Anyway, if there is a way to disable it (perhaps by getting it to recognize that Haruo has already answered at least a lot of the questions), that would be wonderful. It actually asks me twice each time I visit, because it comes up before I log in and then again after I log in. 

Thanks!
