Talk pages: Archive or leave alone others' comments edit
Hi Guo! Please don't erase others' comments on talk pages (unless it's your personal talk page, here), as you did at Talk:Regression discontinuity design. You may archive old comments, but not erase them. Thanks! Kiefer.Wolfowitz 14:08, 16 July 2011 (UTC)
Disambiguation link notification edit
Hi. In your recent article edits, you've added some links pointing to disambiguation pages. Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ • Join us at the DPL WikiProject.

Hi,
You appear to be eligible to vote in the current Arbitration Committee election. The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to enact binding solutions for disputes between editors, primarily related to serious behavioural issues that the community has been unable to resolve. This includes the ability to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail. If you wish to participate, you are welcome to review the candidates' statements and submit your choices on the voting page.
