Here’re The Resources To Learn Modern Greek! – “I kinda like languages” blog
Follow the link above to see a very detailed post about resources of any kind for learning Modern Greek language. Be sure that Lyzazel (the author of this blog) did a very good job himself creating an Alphabet lesson, but also some Grammar lessons. Most of the content suggested there is free and some of them I have already mentioned on my blog..But I am sure that you will find something useful there if you take a look.
