Mistake can happen at any point in time, am sure he must have wrongly visited the board and forgot himself there before realizing the need to make a post, while he might not thought about being on the Ghanian board before making the post, this is why we should always check and reconfirm before making post to avoid making mistakes, some could also be distracted before they realized that they have already done something wrong, in his case, we can help give him a PM to inform him of the mistake he did.
