Base of short answers

Base of short answers is a base of short questions (ussusaly one word) with a base of short answers (all together 160 characters). In this project I created a closed system of learning, apropriate for an school (pupils in the beginning create questions and answers, and after that use the base of short questions and short answers for learning on mobile phones and for testing in crosswords.) To avoid the monolitic view of the base on the screen I created several altenate systems for learning: free telephone number and softweare for crosswords. Al the systems are created in my technologies and tools, based on PHP language.
