Nima,
Congrats!
During the last virtual bugs bashes we have been working on portlets (forums, calendar, news, file-storage, dotlrn portlets, etc.) improving accessibility (html fixes, adding title for A tag, fixing tables, etc.) and fixing also missing i18n keys. Please, be aware of that when you'll commit your work. Feel free to email me if you have any questions/problems, I'll keep an eye on my mail during all day.
