That's an unusual request.
After being with us for 2 1/2 years and making 84 posts, may I inquire as to why you no longer wish to be part of the iRV2 community?
To answer your question, a moderator or administrator will have to delete your membership which will then remove the profile. Unless deleted, all your posts will remain and your user name will show with brackets. (Example: <Pushin40>)
Send me a PM or email if you don't wish to post publicly.
