With Aha! Ideas Advanced the ideas portal can now support multiple languages. The portal will automatically detect a user's browser language and display the portal in that language (assuming the language is enabled for the portal).
However, some users may not have their browser set to their actual preferred language due to IT or other restrictions. It would be great to let the portal user pick their language in the portal manually. Perhaps add a user profile setting or a flag selector at the top of the portal.
