Forum:SH:Comic Variants

Hi all, I have signed up to the site today, having met some of you at CVI. I am keen to get involved in helping keep up to date details on the comics and books which is my collecting area. I have a lot to learn, as am not a tech savy guy - but am enthusiastic. To cut a long story short, my question is regarding variant issues on the comics. I note that these are not detailed in the comics. Is this a conscious decision, or is this an area that I can help expand on. Secondly, Would it be further appropriate to keep a real world list of variant issues?
