It's a pretty standard Flash into, nothing completely out of the box there. Unfortunately, i can't read a thing - i don't speak Swedish
All the more important; you have no distinct favicon, reuse the rings from your logo, that's a step in the right direction.
Also, it takes WAY too many clicks to get to the actual forum. Unless you have great content in between the flash intro and the actual forum, you're going to loose a lot of users in between. I'd move the forum directly behind the flash intro.
Flash intro is only suitable for eCommerce sites (ex: online stores, to highlight discounted products, new arrivals, etc) IMHO. But if you really want a flash intro, I suggest you to use exact color scheme with your main site.
The layout of your main site is not well designed. There are empty spaces under your logo. Try to put something to fill the space (news highlights, newsletter registration box, etc).
Your site title is pretty small. Try to make it bigger.
The forum template is pretty basic. Try to search the net for free phpBB templates and I'm sure you will find some interesting free templates.
When I get the time I will make the changes. I am only in charge of the forum and my business partner have cotrol of the homepage and the apprasial part.
