already posted in irc, but gotta try to reach some people here too.

i was trying to setup a n-back task in my survey. similiar to this one cognitivefun.net/test/4 - except that i am doing it with vowels. at the moment i am realizing it with a new question for each vowel and a timelimit on the question. then it hops to the next vowel. the user has then to enter whether its the same vowel or not. but this is kinda unsexy. is there any possibility to optimize this? im using limeservice

thanks!
