Congrats on your achievement. This is another example for forum users especially those who are new here. Who are thinking it's impossible to rank up by earning merits. Even you join after me but your growth was faster than mine. You spent a decent amount of time and you deserve this achievement. Hope the activity won't prevent you to become Legendary although you are a true Legend.
Wishing you all the best, community expecting more contribution from you.
That's about 10 hours per day! I'm not sure exactly how the forum counts this, but it's a lot!
I am pretty sure login time counts after login in into the browser until close the Bitcointalk tab. Doesn't matter you are browsing something else in another tab, still, login time will count.
