775849 556106Hi this really is somewhat of off subject but I was wondering if blogs use WYSIWYG editors or in case you have to manually code with HTML. Im starting a blog soon but have no coding expertise so I wanted to get guidance from someone with experience. Any aid would be greatly appreciated! 905266
