I need to developed a website for different countries with the same language but with different content. Is some extension compatible with RT to developed this web site?
I was checking this solution and is a possibility, however my problem is because the home content and everything else is different for the website of each country. So I don´t know if is possible to install a different R T launcher in each sub domain and synchronize the main data base to make it easier, due to the web master in each country need to update the information just for his country website. Is another solution possible?
If you choose your sections and categories the right way, it isn't too bad. Then you make each countries menu link a "section blog" menu item instead of the frontpage component.
There are some multi-site components out there if you check the joomla extensions site, but remember that you have to update all of those individually when it's time to upgrade. It ends up adding thousands of extra files to your hosting also.
Either way you do it, you're going to have to put some work into it, it's just a matter of where you want to do the work.
Also, Joomla 1.6 is coming out soon and will have much better Access Level Control for users, so if you plan on upgrading to 1.6 when it's available, you'll be able to limit your users to only posting in the country section allowed. It will also have an infinite category structure meaning categories in categories in categories and so on.
I was thinking to use joomfish as a multilingual extension, for countries with different languages, but it doesn´t work for countries with the same language. Maybe you know another extension similar to joomfish, but to manage information for countries, compatible with R T?
I was reading a document from google which suggest to use a different sub domain or directory for each country or language (makier easy for SEO). Can I create a a sub directory or sub domain to aim to the content for each country or language?
Did you read through the post that I linked to in my first reply? That shows you how to have the subdomain structure from one installation.
The only difference is that instead of college skydiving clubs, you're listing countries. Either way you do things, it's going to be some work to get to your solution.
I am checking the items for each menu in the new web site and reading again your post, and I think is the best solution. I am starting to developed using crystalline. Just I am not sure how you link each club with the respective sub domain.
When I created a new menu for say, "Georgia Tech", the first menu item would have an alias field. That is where I created the url for the new sort of subdomain, "georgia-tech". Even though there wasn't a direct menu link, after setting this in the backend, I could then visit it be going to "mysite.com/georgia-tech".
