Just a little note: when editing, it's polite to include something meaningful in the summary that says what you've done -- for example, if you add a new solution to a task, it's nice to put something like "added language". Adding the summary takes little time, and it really helps others.

Under Special:Preferences is an option for the wiki to remind you to enter a summary if you forget; I highly recommend turning it on. (Look for "Prompt me when entering a blank edit summary" under the "Editing" tab.) -- Erik Siers 21:03, 9 October 2011 (UTC)
