I experience frequently that either content is missing or linked to the wrong targets. E.g. Survival phrases 58, Premium Members sessions -- none of it's contents can be accessed -- at least not with a Firefox browser, which used to work fine in the past. When I try to leave a post, an error message "invalid content" is displayed. In many other cases, the audio files are mixed up. -- No problem, errors can happen, but it seems to me there is no QA involved at all, that no one even tries/tests new contents just once from the user's perspective. You could avoid a lot of user's frustration with such a simple test.
