When I checked the Google AdWords, you paid say $20, and then each time the ad is clicked a portion of that is deducted which I think was nearly 10%. I'm still considering it, but I don't know.
I think folks register expecting to be able to see "more" stuff, or perhaps so their last post read is shown so they don't end up re-reading what they once read.
The welcome section was merged into the PH Member Interview section. I've been thinking of re-titling that, just don't know what would entice people to read it.
I've always got it planned that when a member registers, they receive a PM with a little information and a link to the "how i found PH" thread.
The spam members are really getting on my nerves lately. It seems every morning I hop on here, I have two or three members to delete. PH isn't that highly trafficked so what's their motive? I don't get it. I need to figure out how to block yopmail.com emails.
