Constructive contributions to Wikipedia are appreciated, but a recent edit that you made to User talk:Snowolf has been reverted or removed because it was a misuse of a warning or blocking template. Please use the user warnings sandbox for any tests you may want to do, or take a look at our introduction page to learn more about contributing to the encyclopedia. If you think I made a mistake, or if you have any questions, you may leave a message on my talk page. Block templates are only supposed to be used by administrators or clerks.
