I don't really spend any time outside the patch I'm looking after now so it's a matter that I'm not concerned with or qualified to speak to beyond that.
The term "Senior Member" has confused me a little. I was struck by it some time ago as I composed a remonstration for someone for making a very obvious error for a "senior member" when I noticed they only had a half dozen posts and really had no clue what they were doing. That's when I understood what it took to "graduate"
The idea that all one needed was a few posts of any quality to attain a rank seemed odd.
That being said, it's not something that has ever impacted greatly on what I have been doing so not worth making anything of.
Redefining the structure and titles might be a idea if the need for organisation is something that niggles, but it's really up to everyone else.
