How many pages did you have a few or a lot? You could set something up on your server or have your host set something up for you. See the 300's for information on redirects and which you need or would want.

For these the pages will still have to exist.

Well i'm getting 824 404 Errors, and this is a complete change for my website structure.
Another problem is that i usually on all my threads i link to other threads in my webpage and i must edit all links?
Please, if there is a solution ...

Go with a 303 server redirect would be my recommendation. I've only had my host do this for me for requests coming from index.html to index.php when index.html was deleted (the 404 problem). I'd think they can set up the 303 to remove that directory name though and just load it in the root.
The links should be corrected with the server redirects also.
