I generally check once in the morning before work, and then periodically throughout the day when get back from work or when it's a day off (or I'm not doing anything else that day).
In the morning before school, and, when I don't have any homework or assignments, several times during the afternoon through to about 10:00 at night
I check it every day, I might not be able to reply to messages or talk to people but I still check it.
I usually check it about twice a day. I don't work outside the home so I really don't have a schedule to follow.
I'm here usually every morning when Kass isn't around and clean up the spam and anything else that needs to be done. 4 or five hours every morning and a couple hours in the evening every day. Part of being one of the Admins on the site.
I check it every so often.
I get in the site at least once a day to check it out & see how's everyone & everything going in the community.when i get the time to be here more regular, i keep checking the series of the questions & some members for their answers & questions in particular. However, throughout the day i get in more specially when i get notifications on my mail. If someone comment or there be a discussion i need to check it fast maybe i'll response later but i need to read it as fast as i receive my notification. Also i don't like to let my notifications go so high, i get them cleaned up as fast as it gets there.
