Hey, Welcome to the forum, but if you like to make your ANN thread more appealing, I suggest that you buy a copper membership.
If you don't know the purpose and how to buy, you can read about the statement of admin.
By popular demand, newbies can now pay to have some of their restrictions lifted. If you pay the fee, you become a Copper Member, and you can post images.

This is very similar to the PowBit thread, and I am not sure what kind of marketing is this. They just drop a few words here, big words, and that's it... they don't have a site, or any images to show what are they doing/planning. So I don't think they will buy copper member, maybe one day when they decide to show more. But since they didn't share more we can't know when will it happen.
I think they feel like they are doing some sort of SEO work for their sites by introducing them like this, but they are actually doing nothing. There might be a few people wasting their time searching the site, but that ends after 1 day. If these sites are legit and actually do a proper announcement, they might give themselves a proper chance to become a place users would visit.
