While it is fine to delete your post before you have had any replies it is very annoying, and discourteous, to delete posts after members have taken the trouble and time to reply.
There are a few members who do this regularly. Please stop doing so or you will find that members will make a note of who you are and they will refrain from answering you in the future and may even pass your name on to other members who may also decide to ignore your posts.
