If i copy my blog's article to here Can i keep my blog link?
a web hosting review.

Given that this is your only post, I don't believe you have access to post links at this time. This is to prevent people from spamming their sites and affiliates all over the forums.

You'll want to post a bit more first to establish a reputation and build up your post count :)
