Many learners of Japanese start out by writing in romanji. While this is ok, it is not going to help your Japanese progress. Besides, kanji looks really cool! So, here are some links for helping to type in and read the Japanese characters.
If you have microsoft, get your hands on the IME. It's free and it will help you read all of the East Asian languages. I used this when I had an English OS and it worked REALLY well.
This is by far my favorite online Japanese dictionary: by Jim Breen. If you see a character on here that you don't understand, you can paste it in the dictionary and get the meaning.
As with many people, grammar is my weak point. I use JGram to study.
for a good, all-around study page, check out Meguro Learning Center's resources page. It has everything for all levels. Plus, all the material is free!!
I hope that these helped get you prepared and ready to take over the new Japanese Language forum! If you know of any other sites that will help people see, type, and understand Japanese, let us know!
