I'm afraid you will either have to use another signature or scale yours down. Our signature rules are strict in order not to clutter the forums with atrociously heavy-load or large ones.
I saw a lot of people being creative with the restrictions, so I believe it shouldn't be that hard.

Creating a thread exclusively about it would be the fine example of blunt advertising I'm afraid.
Good thing you have asked though, so it was a good call.

As far as I'm concerned, you are free to use a non disruptive signature about your site though. In some occasions, if you think a link towards one of your blog article is relevant to a given topic and that you just can't copy the essential part of it (due to its sheer size for instance), then you can put a link and give more details. Something of that kind.

Cool site and loved the Tales of Symphonia review (I played my copy of the game until it stopped playing). What do you think of the second game in the series (I still have not completed it so no spoilers please).
