Welcome
Hello, Yujunliu and welcome to Wikipedia! It appears you are participating in a class project. If you haven't done so already, we encourage you to go through our training for students.

If you need help, check out Questions, ask me on, or ask your question on this page and then place  before the question. Please also read this helpful advice for students.

Before you create an article, make sure you understand what kind of articles are accepted here. Remember: Wikipedia is an encyclopedia, and while many topics are encyclopedic, some things are not.

Your instructor or professor may wish to set up a course page, if your class doesn't already have one. It is highly recommended that you place this text:  on the talk page of any articles you are working on as part of your Wikipedia-related course assignment. This will let other editors know this article is a subject of an educational assignment and aid your communication with them.

We hope you like it here and encourage you to stay even after your assignment is finished! Chris Troutman ( talk ) 01:54, 27 August 2014 (UTC)

Hello, I noticed that you may have recently made edits to Education Program talk:University of Southern California/Ecological Factors in Design (Fall 2014) while logged out. Making edits while logged out reveals your IP address, which may allow others to determine your location and identity. Wikipedia's policy on multiple accounts usually does not allow the use of more than one account or IP address by one person. If this was not your intention, then please always remember to log in when editing. Thank you. Chris Troutman ( talk ) 20:43, 23 September 2014 (UTC)

Hi there! Thank you for your contributions to Wikipedia.

I noticed your recent edit to Green infrastructure does not have an edit summary.Please be sure to provide a summary of every edit you make, even if you write only the briefest of summaries. The summaries are very helpful to people browsing an article's history.

Edit summary content is visible in:
 * User contributions
 * Recent changes
 * Watchlists
 * Revision differences
 * IRC channels
 * Related changes
 * New pages list and
 * Article editing history

Please use the edit summary to explain your reasoning for the edit, or a summary of what the edit changes. Thanks! Chris Troutman ( talk ) 15:19, 10 November 2014 (UTC)
