Languages

The Wiki software can display many different languages.  To change the language you will see, make sure you are logged in; go to the top of the page and click on "my preferences"; select "User profile" tab; and change the Language field toward the bottom of the page.  This option does NOT change the Page contents in the Wiki.  You are encouraged to translate the information below into your own language or any languages you are familiar with. 

To Translate Pages into Your Language

Open a separate web browser window http://translate.google.com/translate_t. This connects to Google Translation.  Copy the address line from the Wiki Page name into the Translation window; select English as the source language and your language as the destination language.  Feedback on how well this works should be posted in the IAP Wiki forum.

You are welcome to add specific language translations to this page.

All pages in the Wiki should be in English.
