Thank you for your your contributions to ArchWiki. Please make sure to include an edit summary with every edit, even minor ones, as this is helpful when browsing an article's history. I'd suggest you to go to Special:Preferences and check "Prompt me when entering a blank edit summary".
Hey Alad, thanks for the hints. I didn't know that it is recommended to comment every change. I'll try to do better in future :)
