Once two weeks expired I get the new account and I have a chance to remember/repeat the passed kanji symbols as well honestly, practice makes perfect. and nothing but this really helps.

Use Anki (search in the web how to use it), and make your own decks: a) Be familiar with Japanese pages. It can be Japanese Twitter accounts, newspaper for kids, manga. Whatever you want, but you need to expose yourself to the vocabulary. b) Every time you encounter a word you don''t know, search that word in this dictionary http://www.ottix.net/cgi-bin/wwwjdic/wwwjdic?1C And put it in your Anki deck. That's the only way to learn. Don't learn Kanjis individually, it doesn't work. Learn words, you'll learn both kanji and vocabulary. Don't take words from a list or something (unless is a really obvious noun), learn words as you encounter them, you need to see them in context. Use Rikaichan/kun to easily know how to read a certain word.
