:Nopetro, you're still not using edit summaries and still copy/pasting from sources.  The copying puts wikipedia at legal risk.  If you were in most universities today, you could be kicked out for doing this.  It also causes other editors to need to check all of your edits to make sure they are good.  I understand that English is not your first language, so maybe it would be better to ask on talk pages for help inserting information, so editors who are more comfortable rewritting the text than you are can make the edits.
