mastermovic we are sorry for the inconvenience you are experiencing in editing your older posts. Once you’ve made a second post you are not allowed to edit previous post. This is so as not to distort the flow of a discussion and to discourage abuse/spam.
The ability to edit post indefinitely is reserved for our VIP members. Modalities for becoming one would be communicated in due course.
In the meantime, you can private chat me with the the content you want to replace your post with and a screenshot of the post you want replaced. If approved, it will be edited accordingly.
