KF is a great site for kitesurfers all around the world. I find it very helpful to stay up to date with all news related to this sport. However I think that you could improve a lot your site by simply making some changes.
Looks like this site is not designed by a professional (maybe you or a friend of you "designed" it some time ago

Let me name some examples:
1- Mobile navigation sucks! Open KF in a mobile device and try to tab on a forum post displayed at the homepage. The text has such a small size (14 px) and small margin that the possibility of missing the link and tabbing the upper or lower links are very high. When browsing KF on my phone (5,5' screen) sometimes I miss 3 times the desired link. See picture attached
2- Too many useless text and icons on the header. See picture attached
3- Links inside a text post. When clicking a link inside a body message, the new site opens in the same window. Do you know what it means? The possibility that the user doesn't come back to KF is very high! Bad for you and for the companies that advertise on you your site. You can easily solve it by opening new links on secondary tabs.
4- Too many forum sections (25!!). Some of them (Women's & Fitness) don't even have a hundred of topics.
5- A blue logo in a blue background doesn't make much sense. A contrast background color like white would make KF logo much more visible.
Please take it as a constructive criticism from a guy that spends few hours a day designing sites
