Memo is a recursive acronym standing for Memo Enables Memory Optimisation.
Memo's purpose is enhancing its user's ability to remember foreign words and phrases by regular repetition of a properly chosen material. Memo can be used to regularly send emails containing packs of words or phrases to be translated by the receiver. User replies to the e-mail filling in the answers. Memo parses the reply and updates its internal database with user's results. Sets of questions for every test are chosen basing on user's performance in previous tests -- the words that are most difficult for the user are sent more frequently.
