The SRS page of the wiki has lots of links to useful things. The Supermemo pages especially have good advice on formulating knowledge as cards.
A few years ago I tried learning Esperanto via SRS, and it seemed to work well, but I stopped reviewing the cards because I realized that it was basically a waste of time—it was less entertaining than other sources of entertainment (especially once you’ve learnt all the cards and only have reviews left to do), and useless relative to other types of work I could do. I also tried Lojban but gave up for the same reason. Of course, your mileage/situation may differ.
