Please refrain from making test edits in Wikipedia pages, even if you intend to fix them later. Your edits do not appear to be constructive and have been reverted. If you would like to experiment again, please use the sandbox. Thank you. Materialscientist ( talk) 23:59, 14 October 2014 (UTC) reply

Please refrain from making unconstructive edits to Wikipedia, as you did at Chemical change. Your edits appear to constitute vandalism and have been reverted or removed. If you would like to experiment, please use the sandbox. Administrators have the ability to block users from editing if they repeatedly engage in vandalism. Thank you. __ Just plain Bill ( talk) 00:24, 15 October 2014 (UTC) reply

You have been blocked indefinitely from editing for abuse of editing privileges. If you think there are good reasons why you should be unblocked, you may appeal this block by adding the following text below this notice: {{ unblock|reason=Your reason here ~~~~}}. However, you should read the guide to appealing blocks first.
