[kde-edu]: kde-edu Digest, Vol 74, Issue 20

Fri May 29 13:44:06 CEST 2009

People keep sending me the samples for KTurtle, at this moment I don't have
time; because of a technical course >>>letter of the seaman 2nd class, that
start's today.
On the weekend I will try to make a file text with the good's.
