the picture under your avatar, wich is a muffin now, portrais how much posts you made on this forum.
if you just joined this forum, you will have less then 5 posts, wich makes you a 'blank flank'.
now that you posted 5 times or more, you have progressed to the status of 'muffin'.!
if you want to know how much posts you need to get a member title, you can click on the muffin you have now and a pop-up should show you everything you need.
