I am searching for an extension for blogging. What I want is something like joomla.org with subdomains for each blog, like myblog.joomla.com . I found easyblog, but it doesn't give for each blog a subdomain. Is there any blogging extension?
Easyblog is a good extension, you can use it. The problem of the subdomain is not something that you can manage from the blog extension.
You have 2 options:
- create aliases subdomain, for example blog1.joomlasite.com, blog2.joomlasite.com... Then install VirtualDomain extension, it will help you to manage your subdomains: http://extensions.joomla.org/extension/virtual-domains
- create subdomains and set up them with a dedicated joomla installation and its own easyblog extension. But it's not a good solution because users will need to register on both site/blog
First option is the best one in my opinion.
It's kind of unclear what you want to do... but yet I what I understand is that you want to be able to create new sites/blog instances from the same Joomla installation.
You can have a look at this question here about multi-sites management:
Also, this question How can I create a menu item on a different subdomain? suggest a method to create link menu items as being subdomains ... But at the end it depends on the size of your project if multiple subdomains blog would be efficient to be managed under 1 single Joomla db instance.
