<div style="padding: 5px; background: #f9f9f9; border: 1px solid #39f;">Greetings and welcome to [[Wikipedia]]! Thanks for [[Wikipedia:Your first article|starting to contribute]] to Wikipedia. If you have not yet [[Wikipedia:Why create an account?|registered a user name]], I encourage you to do so, because while editing anonymously is great, anonymous users sometimes don't get to experience the full [[Wikipedia:Community portal|community]] aspect of Wikipedia. [[Special:Userlogin|Registering]] a user name will give you an identity on Wikipedia and allow you to do several things anonymous users can't, such as vote in polls, set preferences, and upload images. You may wish to review some or all of the following pages to aid you in your editing: * [[Wikipedia:Welcome, newcomers|Welcome!]]<br> * [[Help:Contents|Wikipedia Help]]<br> * [[Wikipedia:Tutorial|Wikipedia Tutorial]]<br> * [[Wikipedia:What Wikipedia is not|What Wikipedia is not]]<br> * [[Wikipedia:Manual of Style|Wikipedia Manual of Style]]<br> * [[Wikipedia:Avoiding common mistakes|Avoiding common mistakes]]<br> Also, if you post on talk pages, remember to sign your username with four tildes <nowiki>(~~~~). If you have a specific question about how to do something on Wikipedia, feel free to ask on [[Wikipedia:Help desk|the help desk]]. Also, remember you can create and edit your own user page to include information about yourself and anything you may find useful. Feel free to drop me a comment or question on [[User talk:Solver|my talk page]]. Welcome again and happy editing, ~~~~. </div>
