There has been a very short discussion about this in theCalender thread and the Need to talk to a Ranger thread, but it doesn't seem there are any great differences of opinion about this, so I thought the best thing would be for this to have a thread on it's own, for introducing the feature and for collecting people's requests and ideas.
So, here's another nifty thing for your posting pleasure:
You can have a very small pic between your title and your avatar!
You can choose from a wide variety of pics that are already available on the b77 admin panel.
In order to see them, you'd have to be an admin, of course, but thanks to our training board, you can be that!
So, what you have to do is: go to the Ranger training board, register and have someone make you an admin.
Go to the admin panel as described here and pick a rank image.
(Thanks to Holby for the link to the phpbber support forum.)
Let the Rangers know which rank image you want by posting in this thread.
You can also make your own rank images!
Make the image, upload it to photobucket (or another album that enables direct linking to pics), and let the Rangers know that you'd like to have this put under your rank!
Have fun!
