This is not a Message Board relating to the Genealogy of Ulysses Grant. Please direct those types of questions to the Grant Family Forum. Occasionally there is no concrete reason for deleting a post. One person is making the call, which is based on perception. It comes down to weighing things like past reputation, intent or the way a specific poster or all posters will react.
People frequently write and ask why their post was deleted.
The reasons are generally covered in the guidelines. Don't take it personally, sometimes space consideration is the sole motivating factor in deleting a post. The purpose of this site is not to answer all of your questions about Grant. Rather, it is to introduce the man and his life to a diverse audience, and to offer avenues by which you can answer your questions yourself. Having someone else answer all your questions would rob you of the pure joys and yes, frustrations of discovering Ulysses S. Grant.
