Hello, I noticed that you may have recently made edits to Closed form summation formula while logged out. Wikipedia's policy on multiple accounts usually does not allow the use of both an account and an IP address by the same person in the same setting and doing so may result in your account being blocked from editing. Additionally, making edits while logged out reveals your IP address, which may allow others to determine your location and identity. If this was not your intention, please remember to log in when editing. Thank you. –Deacon Vorbis (carbon &bull; videos) 16:03, 26 October 2018 (UTC)
 * If this is a shared IP address, and you did not make the edits, consider creating an account for yourself or logging in with an existing account so you can avoid further irrelevant notices.
