It is not responsive.
Can I put backlink in your forum as a signature ?

create responsive website.

As others have stated, your website is not responsive. The design of your site also looks seriously dated. From an SEO perspective, your meta description is too short and your images don't contain alt tag text. It would also be a good idea to use browser caching, so returning visitors can load your pages faster.
