5 to 10 times a day for me.
3 rail 027 is the place I go to most.
and since every one tracks everything.
I also use it to get to as many of the vendors as I can.
If I am looking to see what is up at Western Depot I will hit refresh until the ad shows up then click on the ad.
Or if I want to go to RMT I use the forum as my jumping off point
