  7. Hi ho!

    For a non-MT/MLS student (like me =P), it's hard to understand some portions or terms in this blog. Acronyms like "SI" and "MIR" are unknown to some people, so if it's not much of a bother, you can provide the abbreviation and it's meaning. But.......... your readers can google it, but it'll be + work for them haha =D Anyway, i think this blog is not intended for outsiders like me (o_o)

    But then again, it's an OK blog. If you put too much terms, definitions, or explanations, it'll be boring to read. It's simple and easy to understand...
