ooh that will be helpful :)
here's where i practice reading hiragana
this one will actually teach you kanji as well
http://www.readthekanji.com/
cost: parts of it are free, some more advanced parts you have to have a paid membership for
registration: you have to register but it's quick and easy and will help you keep track
description: i actually haven't touched the kanji yet, once you register you can go to your settings and switch it to hiragana, this is what i've been doing. it shows you a sentence in hiragana, with one character highlighted. you have to type it in romaji. at the end of a round it makes you re-do any you got wrong. being presented in a sentence is helpful, sometimes you can figure out a character if you know the word or phrase, rather than just working from memory. if you are looking to learn kanji from it, it does follow the jlpt. they are in the process of updating the site to conform to the new jlpt standards, and there is a blog as well that goes more indepth into kanji reading

description: it's like flashcards, shows you a character in hiragana or katakana, and gives you 3 or 5 choices in romaji and you just click the one you think is right. sometimes it's process of elimination, if you don't know what ほ is but you know it's not ta or chi, then you can still get it right. i actually was able to memorize kana i hadn't learned in my other lessons yet by using this method. you can also choose which set of kana you want to practice. basic set, marks (like 'ba'), doubles(like 'kyo') or the full set which has all of them. it does repeat a lot but that's what helps them really sink in. i use this more than the other site because i can go through more kana in less time, but it is strictly just characters, no words... so the other site is slightly more useful since you can learn to read some basic sentences at the same time.
