I used to visit there often but I dont like the layout they use for their forums these days. It was much easier using the layout that they used to use which was similar to how DP is laid out.
If your looking for information on SEO you need to find a forum from an SEO company. I highly recommend the SEO forums at SEO.com. All the staff members are experienced SEO specialists with a track record of success.
Use the use the search feature and you ll find many of them, but nothing like DP ...believe i just found DP and there is nothing better than this one.
my favorite Forum is only DP and i am using another 2 to 4 forums webmaster-talk.com ,forums.build-reciprocal-links.com and some other but DP is only one forum for way of get earn fast money.
