Hi folks, we've been using LimeSurvey for the last couple of years to run Wikimedia surveys, but as we pushed it to its limits, we've surfaced numerous problems, including security vulnerabilities and major concurrency issues.  It's got many of the right capabilities and may be fixable, but it would take a very significant amount of effort to do so. Do folks on this list have experience with other good open source survey tools that you've used at scale, or seen used at scale? Yes, there's always the option of rolling our own (perhaps building on Jeroen's new survey extension for MediaWiki) -- but do keep in mind that surveys can get pretty technically complex, so that may be prohibitive for some of the surveys we're planning to run. We're looking at both open and proprietary solutions, but if anyone has any tips, they'd be much appreciated. I'd like to avoid lock-in to a proprietary solution if at all possible. :-) Thanks, Erik -- Erik Möller VP of Engineering and Product Development, Wikimedia Foundation Support Free Knowledge: http://wikimediafoundation.org/wiki/Donate _______________________________________________ Wikitech-l mailing list Wikitech-l(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
