Dear friends I have a Forum which is only 1 week old. i have nearly 65 members registerd and less than 300 post, My question is...Whether I should place the ad at this stage??? Or should I wait until my site get established?? Will it cause a bad impact on my users??? Please help me.
As long as you blend the ad well and don't overwhelm your visitors, I highly doubt that you would see a negative reaction.
