Welcome to the Translator group
For background on how we are working, take a look at Tasks_and_Tools - remember this is a new system to us, so we are constantly evolving.
If you would like to experiment with the system, one thing you could help with is copying existing Spanish translations onto the new system. You will notice that we have retained the old multilang bar during this changeover period.
As well as Talk pages here, you can ask questions on #kde-www.
