Could I ask please if you link to a blog to put it in your main post?
Many of us have signatures turned off, so unless you say something about the blog in the post, we won't even know you have a blog. I see nothing wrong with saying "Hi, I went to the matches and did a whole write up on my blog." and then post the link. I don't think Action Jackson can arbitrarily make that a forum rule.
I don't get why it's somehow wrong to put the link to your blog in the post.
