The little sign is there to encourage people to participate - and to start that participation by simply posting an introduction of themselves.
We have been online for almost 20 years and found that many people were just lurking and reading posts but not actually participating in the forums. If people don't participate then eventually the forum will go away. (which would be a terrible loss of a great resource). That's why the little man was placed there - just to encourage people to at least jump in and introduce themselves. You should notice, now that you've made at least one post, that when you are logged-in you won't see that little man any longer.
With that said, now that you've got that complaint out of your system, how about replying here and telling us who you are and a little about your British car(s). You will find if you give us a chance that this is a pretty friendly and helpful forum and it's likely you could be a big help to others as well.
Welcome to BCF - now tell us about yourself.
