I hope you enjoy editing here and being a Wikipedian! By the way, you can sign your name on Talk and vote pages using three tildes, like this: ~~~. Four tildes (~~~~) produces your name and the current date. If you have any questions, see the help pages, add a question to the village pump or ask me on my Talk page.

Matrix
editHello. I am sorry, but I felt that I had to revert your contribution to matrix (mathematics). The section is specically about important types of matrices, which have a special structure. I doubt think that idempotent matrices fall into this category. The list of matrices has all special types of matrices, and the idempotent matrices should be listed there. As it turns out, they weren't, so I added your contribution there. Cheers, Jitse Niesen (talk) 00:09, 23 October 2005 (UTC)
AfD Nomination: The Largest Facebook Group Ever
editHello, and welcome to Wikipedia! We welcome and appreciate your contributions, but all Wikipedia articles must meet our criteria for inclusion (see What Wikipedia is not and Deletion policy). Since it does not seem to me that The Largest Facebook Group Ever meets these criteria, I have started a discussion about whether this article should be kept or deleted.
Your opinion on whether this article meets the inclusion criteria is welcome. Please contribute to the discussion by adding your comments at Wikipedia:Articles for deletion/The Largest Facebook Group Ever. Don't forget to add four tildes (~~~~) at the end of each of your comments to sign them.
Discussions such as these usually last five days. In the meantime, you are free to edit the content of the article. Please do not remove the "articles for deletion" template (the box at the top). When the discussion has concluded, an administrator will consider all comments and decide whether or not to delete the article. -- Netsnipe (Talk) 22:07, 24 August 2006 (UTC)
File permission problem with File:Warsaw uprising straight.jpg
edit
Thanks for uploading File:Warsaw uprising straight.jpg. I noticed that while you provided a valid copyright licensing tag, there is no proof that the creator of the file has agreed to release it under the given license.
If you are the copyright holder for this media entirely yourself but have previously published it elsewhere (especially online), please either
- make a note permitting reuse under the CC BY-SA or another acceptable free license (see this list) at the site of the original publication; or
- Send an email from an address associated with the original publication to permissions-en@wikimedia.org, stating your ownership of the material and your intention to publish it under a free license. You can find a sample permission letter here. If you take this step, add {{permission pending}} to the file description page to prevent premature deletion.
If you did not create it entirely yourself, please ask the person who created the file to take one of the two steps listed above, or if the owner of the file has already given their permission to you via email, please forward that email to permissions-en@wikimedia.org.
If you believe the media meets the criteria at Wikipedia:Non-free content, use a tag such as {{non-free fair use}} or one of the other tags listed at Wikipedia:File copyright tags#Fair use, and add a rationale justifying the file's use on the article or articles where it is included. See Wikipedia:File copyright tags for the full list of copyright tags that you can use.
If you have uploaded other files, consider checking that you have provided evidence that their copyright owners have agreed to license their works under the tags you supplied, too. Here is a list of your uploads. Files lacking evidence of permission may be deleted one week after they have been tagged, as described in section F11 of the criteria for speedy deletion. You may wish to read Wikipedia's image use policy. If you have any questions please ask them at the Media copyright questions page. Thank you. --Min☠︎rax«¦talk¦» 04:29, 4 April 2024 (UTC)
