I think that is redundant. {{OL}} can work fine with template pages (correct me if I'm wrong), just specify the link to the translated template and they show on it.Neil Watts wrote:

{{OL}} for template pages. What do you think about it ?
Included on Orphans template page for testing.
Edit: I found that in the french wiki thread were talking about inconsistency of language names on the wiki. Google Translate didn't told me everything but I got the gist of it. At most cases is better to go with the name that is shown in {{OL}}. Use the English name of the language on places like the language page (/wiki/Spanish, /wiki/Japanese and such) and their specific categories. You can set up a redirect if required for those pages. If you have doubts, feel free to ask here or PM me.
