We are happy to have a sufficient number of expressions in the Portuguese language at OmegaWiki. It shows how OmegaWiki provides the functionality that you will not find elsewhere.
The labels are shown in Portuguese when you have selected Portuguese as your default language. Better still, when you edit in OmegaWiki, the same labels can be selected in Portuguese.
We would dearly love to provide the same functionality to languages like Telugu, Kannada, Abchaz, Guarani.. We can help by pointing out how you can quickly provide a localised environment, we can help by adding the expressions for any languages when we find them. In the end we need people interested in supporting their language.
