Need Help in Content Translation for Entry of Drupal Blog, Forum

Hi! Friends/Seniors,

I am new in Drupal. I am trying to make my site in Spanish and English. All the translating part is working fine except the contents. In the case of normal CMS pages, I did manage by making individual contents for each language. But I am not being able to make my blog entries (also forum entries) multilingual where as the menus and other parts are being changed in respect of languages selection. The languages are being changed through URLs. (i.e. http://localhost/drupalsite/?q=es/blog (Spanish), http://localhost/drupalsite/?q=blog (English default))

Please review the module settings,

Looking forward for your valuable suggestions to fix this issue.

Thanks in advance.

Arpan
