I'd like to limit the number of "seats" in a class and there are at least three options for each class time slot. Is there a way in LimeSurvey to allow 25 people to select option #1 for question #1 and then have that option either disappear or not be select-able when the limit is reached?

I've been researching many registration packages and they are either very expensive or are not configurable enough for all that I want to do. If I can do this one thing with LimeSurvey (which I already have installed and working very well for normal surveys) then I could really reduce my work load and provide a fantastic addition for my district.

Thanks in advance!

Unfortunately I don't think Limesurvey will work well in this context. It is made with questionnaires in mind.

While you can use "quota" to limit certain responses (which would be exactly what you are looking for), the problem is that a full quota means the person is 'screened out' -> the questionnaire is finalized at this point. But you would need to give a warning and then allow to choose another option.
