Welches Plugin

There may or may not be a single plugin solution available. You might need to piece together the various functions from a few different plugins. Such as a custom fields plugin to collect user data in a structured manner. A rating plugin to implement scoring of the sedcards. Some custom coding may be required to tie everything together.

There are many possible free plugins. A couple search links are below. Try out few and see which you like. There are also a number of commercial plugins from numerous vendors that you can find using a general web search. In selecting a plugin, of course its functional description and features are important. Their star ratings are a factor, but don’t focus too much on them, nor the related reviews.

Often the bad reviews come from some kind of misunderstanding. What can be illuminating is how the plugin author responds to such reviews. Do they remain objective and professional? Or do they come across as protective or combative? Also take a look at at their support forum. Do authors actively support their plugin, or are end users left on their own?
