You can use your license key for the Site URL it was generated and on any localhost site of your own. We consider localhost the urls that start with "localhost" or "127.0.0.1"

You can manage as many sites as you want. The only limitation you will find is the max_execution_time that your hosting provider has set for you, when you try to send many contents to many sites.

You need the FTP and database settings. They will be asked every time you want to insert a new site under the section "Sites"

Yes. As long as your hosting provider does not firewall the server you want to send content to.

Sending the content to remote sites takes a lot of time (due to FTP and database transfers) and your hosting provider may not allow that. You can try to increase max_execution_time in the PHP settings but, in the cases you are not allowed to do that, you can try these:

    * Ask your hosting provider to do it for you.
    * Install this component in localhost.
    * Send less content items

NO. You don't need to ask to your hosting provider for any permission to access the database. The access is made via a wrapper that is uploaded to the remote site. What you will have to check is that you have writing permissions in the root directory of the remote site.

It is possible to send your articles to every Joomla 1.0.x or 1.5.x.

Basically, you just need to add the remote sites in the "Sites" menu and then, from the "Send Content" menu, select the content articles that will be sent to your sites.
If you are managing many sites, maybe you will want to classify them into categories. It can be done by defining the categories in the "Categories for Sites" menu, and then asigning a category to each site

First of all, check that the site status is OK and the site is published.
If the problem persists, set the content "Start Publishing" date to null (-).
Also check if the content you want to send is in frontpage in your main site (where the component is installed) or not, because it will stay the same in the remote site.

Your hosting may have a firewall and the remote site is not allowed. Contact your hosting provider.

At this moment, there are two ways of doing this:

1.- Uninstall the component and reinstall it again

2.- Delete the row in the database table [your_prefix]_multip_licenses. Then, execute the component and you will be asked for the key.
