Do you have a recommended platform system for tips?
Wiki?
WordPress?
Joomla?
BB board?
I *might* be able to host a translation mirror as a sub-domain of an existing site. Although, if you have the option, you might have sub-domains for the languages as sub-domains of your site.
They could be managed independently.

Edit.
I've just probed your site and can see that you are using Wordpress. Only issue might be that you will need an MySQL database per subdomain site.
