First, congrats!
Second, I think you become a full Member after 30 posts or something like that. Also, at this point, if you so wish, you can change the wording 9where it says Member) to say whatever you want; if memory serves, I think you aren't allowed to do that before. Note that I changed mine to say "Diesels are our friends".
I think you become a Senior Member after 100 posts, but I'm not sure there...
