Wikisource Sorbian 
As a special case, Wikisource Sorbian can be used for both Sorbian languages. And better staying translation of those two languages would be counted as official requirement. As translation requirements are fulfilled for Upper Sorbian, you should create Wikisource edition on Multilingual Wikisource (wikisource.org) and have project active for a few months. --Millosh (talk) 20:15, 4 August 2012 (UTC)
Fundraising translation feedback 
I wanted to ask for your help. As you may be aware we have been running banners on many language wikis. We have a lot of new content this year and I really want to conduct a thorough review of our translations. This is a combination of feedback from the community, readers, donors as well as those with professional translator experience. This will help us ensure the highest quality of translations used in our messaging.
To help us out with this I wonder if you would be willing to give us feedback for Polish using This Link
