I don't know if it is just me but I find it slightly awkward to answer a question or respond in a thread when I don't know the member's first name. Somehow seems impolite to me not to include a name in my post. A lot of us have our first name as our user name and those whose user name does not include a first name it comes up because it is in the member's User Profile. I don't know how others feel and people may not wish to share their first name but if your user name is not stated maybe you'd consider adding it to your User Profile. Just go to User Profile - About - User Details, there you can enter your first name.
