Writing a post on another thread, thinking of having a data on active profile.
An extension/script which can show the number of active users within the last 24 hours along with the rank.
For ex:
Total Active Users within last 24 hours- 2500
Legendary- XXX
Hero- XXX
Sr- XXX
Full- XXX
Member- XXX
Jr- XXX
Newbie- XXX
This would be somewhat hard to do without keeping a massive collection of information.
AFAIK, the only services which would be able to do this on the backend side are BitcoinTalk itself, and then maybe BPIP.org (considered they have a last active status with their members I believe)
Would have to wait for BPIP to have some sort of API.
