Hi Rym, I translated from English to Hebrew, the most difficult part was actually getting the rtl alignment right, you can see a demo rtl site here. http://inhebrew2.ning.com
I wonder if this might interest you, its a javascript you can add in any text box to allow non signed in visitors to see a translated version of your Ning site. If someone does try to sign in - the site goes back to original language.
Hi,
If you need information on making Arabic NING communities please contact madaher@warmstudios.net
We have translated a full Arabic community on testwarm.ning.com or community-ar.menassat.com
I have a Russian translation from about 6months ago, if you pm me your email I'll send it to you. You can get embed code for a Russian Keyboard here http://www.gate2home.com/?language=ru&lay=2&sec=8
