A request had been made by members last year when the new forum template came into place, to let the member's rank also be displayed below the member's name in the forum. This may or may not be implemented by the Webmasters later.
In the meanwhile, you can check ranks of members here: ISC members list . It will require some effort on your part - click on each membership level (Platinum, Diamond, etc) and you will see the ranks of all the members at that particular membership level in the last column. I do not think there is any other single page where a comprehensive list of ranks of all members is displayed.
Also, since you are a new member, you can refer to this announcement about how the ranking is done: How a member's rank is calculated. This announcement explained how the calculation of rank was changed in order to ensure members who are inactive for a long time (more than 90 days) do not get a ranking & that one needs to get a minimum of 100 points to earn a rank.
Keep smiling...one day life will get tired of upsetting you.
I have promises to keep and miles to go before I sleep.
