I also have today my forums working with YAF 1.9.1 and URL rewriting without problems.

Yes, it's posible.

After 2 years using YAF in http://yaf.herensoft.net/, I added another YAF in http://test.herensoft.net/. I copied the app and put in the web.config board=2 . I use the same database in the two forums.

I can't remember exactly, but I think you must first create with the main forum the second board and after you can use it with the second app.

With the first one (board=1) I can admin all the boards. With the second one I can admin only the second forum.

Web Application Projects provide a companion web project model that can be used as an alternative to the built-in Web Site Project in Visual Studio 2005. This new model is ideal for web site developers who are converting a Visual Studio .Net 2003 web project to Visual Studio 2005. (Released May 8, 2006).

You must download this Microsoft utility here and install it to load YAF with the VS2005.

Yes, I know the server down 1 hour.

I hope the server work normally all the time.

How much long was the message?

You can see my new forum at http://test.herensoft.net.

The forum is new (has few posts) and it is in spanish. But you can see the forum to look the dark theme.

The buttons are done in the http://cooltext.com page as logos.

Thanks Mek.

I was as admin for a new board (not as admin for the host) and I can't see this fields.

Now I have a RSS button for all my boards.

Yes, I can't see the RSS Button in my forums (I work with YAF 1.9.0 last )

Must I to do something in the Admins panels? or can I have another problem about the RSS files?

Thanks

The international support or localized content is a complex problem, more difficult than the static localization.

You can attack it by many systems:
* to have two o more boards, categories or forum, each one for a different culture. I have a YAF forum like this at http://yaf.herensoft.net. This is not a wonderful solution. You must to repeat the important posts in two o more languages. You can work well with YAF like it is today.
* to have a unique board and allowing the users post in one or another language. You can also work well with YAF like it is today. But the users see all the posts (the ones in his language and the other that they can't understand. This is not a wonderful solution.
* as you said, you can change YAF to show only the posts in the user language. We need a new field (culture) in each post, by example. And change a bit the SQLs.
* to have a unique board, but YAF is changed to permit show the info in the smart mode (*). The changes are big. 2 new fields in the posts table and big changes in the SQLs.

(*) Smart mode = There is a main culture. The user can read a post in his culture. If the post is not translated nor write in his culture he can read in the main culture or in the unique culture that it was write. You can have post in only a culture or post in many cultures. This system is perhaps not the best for a forum, but for CMS is very good. I have it implemented at http://www.sareleku.com

I'm not sure, but I think ast-es is the "asturian" language (ast) in Spain (es).

Perhaps the user was using a IExplorer with this language set as main language when he try to read the forum.

Perhaps you must to edit your source as Mek saw.
