Switching to vB will reset all the titles.
The question is do we mostly stick with what we've been using or go with something entirely new? I think, even if no other changes are made, at least one more level should be added. The current list can be found here:

If you would prefer new titles and have reasonable suggestions, please let us know in this thread.
