[SOLVED] 3 questions

Hello,
I appriciate if you help me with these 3 questions:
1. In order to specify a date, there is a pop up calander on date related text boxes. Which fle is loaded on text box onfocus event? I want to replace it with Solar calander. after that, i can deal with offdays() in moder/calander.
2. How can i make the left tree menue text rtl (right to left)? I have moved this menue place to right but i could not change its structure?
3. I have changed the language to Farsi. But still alot of parts are in Eng. I can not find the english words in related PHP files. How can i translate them to farsi then?
