There are a lot of questions that are asked on profile posts. They are sometimes directed at one member, some of whom may no longer post, or are open ones.
It is a bit of a lottery as to whether a reply will be forthcoming as not everyone looks at profile posts.
A better option is to post your queries on the forum where all members will see them.
