Hello,
before you do minor edits like on http://userbase.kde.org/Special:MyLanguage/An_introduction_to_KDE lately, please ask us first. Making such minor changes will make trouble to all the translators, which is in most cases not necessary. But if it is, it is always good to have talked about it first. Reverted for the moment.
I have added instructions regarding markup of an itemized list to Help:Editing#Itemizations. Please consider reapplying my changes ASAP.
