Thanks for uploading commons:File:Megaprime founds.pdf. We have software which can display it but pdf is not really an image format. Can you upload it in an image format instead? See commons:Commons:PDF to image files, but if you created the file then maybe you can save it in an image format with a better result than converting a pdf file.

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.
