Hi, maybe I won't spend hours a day on Wikipedia. As I don't have huge amounts of time to contribute, I won't spend a lot of time adding content. My interest is in improving articles which already exist and guarding against vandalism and tendentious editing.
When using tables in articles, consider using class="wikitable" at the top of the table, like so: {| class="wikitable". This puts a grey border around all the cells, gives heading cells a grey tint, and uses many other common formatting settings without having to spell them all out.
Here are additional resources suitable for new as well as expert contributors:
