At the german subforum new users often confuse the ranks (“Super Senior Member”, “Elite Member”) for the usernames. Since their use is about zero (a user with a lot of not exactly helpful posts becomes a “Elite Member” very fast), I suggest to disable them.
If the software doesn’t allow this, but does allow custom CSS, maybe you could add the following line to hide them in postings?
Just looked it up: ranks can be disabled if we want to.
I agree that ranking based on the number of posts isn’t very helpful. So we can disable it but we can also decide to use a different reputation system to get some sort of ‘authority’-ranking system, or a post “thumbs-up/down” system?
I like marking posts as useful (or a kind of “thank you”). The second plugin seems to be “useful”-only and displaying a overall user rank. Not sure which is one is better. I slightly would prefer the second, on first glance.
But I could also imagine some people not liking such ratings for posts.
