I know you have a solution to this question on HabboBites on the JOBS page. Unfortunately I am having some trouble with joining it tells me that I do not meet the requirement's and that I need to be online for 1 hour excluding AFK time. Yesterday I have been online for more then 1 hour and I had 2 posts with a lot of thread replies... Still it gives me the same message.
Anyone know the answer?

Hmm, you have exceeded the minimum online time. Try refreshing the page maybe? F5 / cmd + R

Even though you're on the page for more than an hour, the actual time is counted only if you are active on the site.

Every 10-15minutes you need to click on some things on HabboBites in order to stay logged in!
