Yeah, a while ago I was away from the forum for 2 days...so there was more than usual to go through when I came back.
Reminds me when I went on vacation for about 2 weeks without seeing Wilders all that time. Logged in after, checked the "New Posts" and over 20 pages. I said the heck with it and deleted the new posts page to zero again for a fresh start.
I put an hour but that really varies. I check it several times a day and some days there are threads that really interest me and other days I just quickly read a few posts.
It'd just be a guess because I too keep a Wilders tab open 90%+ time I'm in front of my PC. Maybe 1-2hrs?
