I spent many years working on and with a range of different automatic translation tools and have expert certification on some of them
See my Machine Translation (MT) tips page and my Language Evaluation Technology website.
There are also 3 Yahoo forums (SYSTRAN_users, Reverso_users, PROMT_users) for these brands of automatic translation software/systems.

A few of my short articles are provided below on how to go beyond the basic online portals (BabelFish, Google), which were not intended for translation postediting touch-up work, and use the software packages:
