http://thejapanesepage.com/grammar.htm Grammar on Grammar
http://ww8.tiki.ne.jp/~tmath/home/index.htm I don't even remember what this is.
http://www.stolaf.edu/depts/japanese/grammar/#B Possibly the best free online resource for learning grammar. About 80 dollars worth of material that some university put online for anyone to use.
http://www.imabi.net/ Not sure what this is, but it's in my bookmarks and sounds japanese.
http://www.bunka.go.jp/kokugo_nihongo/keigo/ I think this website has lessons in a lot of areas, but I only used this page for honorifics.
http://jgram.org/ More grammar.
If you want more help, you can pm me. I think trying to teach basic japanese would be some good review for me.
Another website you should know of is www.tangorin.com
It's an awesome dictionary.
