You may find this a bit intimidating at first, but see [[Wikipedia:Replies to common objections|replies to common objections]] for an explanation of why the system still works.
Although there isare already a lot of articles ({{NUMBEROFARTICLES}} at the last count), Wikipedia is constantly expanding with new articles written by people just like yourself. You can [[Wikipedia:How to start a page|start a brand new article]], or find an existing article and add an entirely new section to it. A simple way to start helping is just to use Wikipedia as you would any other encyclopedia, but when you spot a problem—a [[spelling]] mistake, perhaps, or an unclear sentence—click '''edit this page''' and fix it. [[Wikipedia:Be bold in updating pages|Be bold in editing pages]]; if you can see a way of improving a page,''' do it'''. Don't worry too much about making mistakes; if you do get something wrong, you or anyone else can come along and fix it later. (Note that every version of every page is stored in the database; that means that it's easy to restore an older version, but also that every edit can be tracked).
