Dear LERK. I am writing to you to inform you that you are in danger of losing your adminship on Commons because of your inactivity in the past six months.
If you want to keep your adminship, you need both to sign at the current inactivity run page within 30 days of today's date, and also to make at least five further admin actions in the following six months. Anyone who does not do so will automatically lose administrator rights.
You can read the de-admin policy at Commons:Administrators/De-adminship.
Hello LERK! It is with a regret that I inform you that, following our de-adminship policy, you had your administrator rights on Wikimedia Commons removed today by a Wikimedia steward.
I would like to use this opportunity to thank you for your efforts and contributions in making Wikimedia Commons what it is today (no big words intended!). If you'll feel like doing so at some point, please feel free to re-apply for adminship at COM:RFA. Again, thanks for all the help you gave us, and (hopefully) see you back soon! odder (talk) 14:16, 18 September 2012 (UTC)
Please do not overwrite files
I noticed that you uploaded a file using the name File:Tokyu-railway-6000-4th-unit.jpg. A file by this name already existed on Commons. Overwriting an existing file should not be done except when making minor, uncontroversial corrections, so the file has been restored to its original version. If the file you attempted to upload is within our project scope and is in the public domain or published under a free license, please upload it again under a different name. Thank you!
For more information, see Commons:Avoid overwriting images with new uploads.
