I added memcached to the server and implemented it in tikiwade for caching searches. I also fixed a bug that caused tikiwade to loose its location on the initial search, and also where tikiwade would "forget" what type of search it had done when using the next and previous links. (this is only in the web version, not the iPhone version). I also fixed a spot on the email a listing page where the word will was being repeated (thanks Marigale!).
Sorry it took so long to get an update out. It has been a busy summer.
