Konbanwa everybody! At least it is Konbanwa for me right now.

I would like to add something that I have found very usefull, it's a Interactive Katakana Chart.

Here is the link: http://hem.passagen.se/bomark/japanska/index.html

Unfortunately (for you) it is in Swedish, wich is my first language, but the interactive chart itself is only in Japanese and it shows the Katakana signs and then how to say it.
Wa
ra
ya
ma
ha
na
etc...

When you click the link you get to a page with these three links in swedish:
Lektion 1 - Katakana
Interaktiv Katakana-tabell (Interactive Katakana Chart)
Asienguiden - Japan

Click the one in the middle and you will get to the chart. Now, the really good thing about this chart is that you can click the katakana signs and when you do that you will be shown how to write that sign. Good, neh?

So I say:
Let's try!
It's usefull!
