I tagged a number of scenic pictures, mostly rocky, wave-crashing shorelines. I made sure that a number of paragraphs from the Ensign had been scanned properly, adjusted a Spanish language Primary manual's paging on using our talents, and proofread a German language lesson manual on revelation. I translated instructions for the new FamilySearch website into German.
The crowd-sourcing is a particularly good idea for the translating, and they have a good system set up. You can vote on the translations of your fellow helpers to help confirm that a particular translation is accurate or offer your own edition. Once a threshold number of positive votes are scored, the page is approved. There are helps available throughout of approved terms, similar phrases that have been translated elsewhere, and a Google translation to help you out. You can also sign in to be notified when changes have been made.
I recommend it as a nice way to get in a few minutes of service easily - particularly for my insomniacally-inclined friends and family. Matt 20: "The harvest truly is great, but the labourers are few: pray ye therefore the Lord of the harvest, that he would send forth labourers into his harvest." Jacob 5: "Wherefore, go to, and call servants, that we may labor diligently with our might in the vineyard, that we may prepare the way, that I may bring forth again the natural fruit, which natural fruit is good and the most precious above all other fruit. ... the servant went and did as the Lord had commanded him, and brought other servants; and they were few. And the Lord of the vineyard said unto them: Go to, and labor in the vineyard, with your might. For behold, this is the last time that I shall nourish my vineyard; for the end is nigh at hand, and the season speedily cometh; and if ye labor with your might with me ye shall have joy in the fruit which I shall lay up unto myself against the time which will soon come."
