Chuck I think you need to post 8 more times before the system will allow you to alter your original profile. Lots of ways to do that easily. Welcome other new members, comment on projects, ask questions, etc. You can be at 10 posts from withing a few minutes or by the end of the day at your choice. I think the 10 post rule is for your personal security.
