I love wikipedia, but I am bothered by poorly written, formated, or cited articles. I used to do anonymous edits as I read. Instead, I am going to learn about wiki mark-up by playing with my user page so that I can edit with confidence and leave a consistent record when I do so.
Many editors often wonder how to request permission to use an image they found somewhere, or a section of text from another source. Try using one of thepermission request templatescreated specifically for this purpose so that you do not have to fuss with all the details.
