I saw the date. I just had to post 10 posts before I can PM members. So I did. I would like to buy something someone is selling on this forum. But I can contact them due to the forum rules. I read the rules very carefully and honestly I think this rule is a bit silly. I understand they are trying to get ride of spam, but by forcing people to make posts just for the sake of posts well... is that really better than spam?
You can also click on the user account, and look at their last posts and how long ago they logged in. The user posting the video card for sale last posted to the forum in June - most likely the card is no longer for sale and the user is not an active participant on the forums.
