You can become more social by turning your iLocals.info blog into a community blog. All you need to do to see how this works is to sign in or signup. And you can go to add a new post.

If you want to create a community blog for your own niche or turn your blog into a community blog (with or without member restrictions) go here for more technical details.

How to as explained by the creator of the community blog plugin:

Community Blogs settings are configured in the Settings > Community Blog admin form which is available to blog admins.

• Enable this plugin: which turns off new user registrations but leaves the plugin activated
• Default User Role: for new users as Editor, Author or Contributor
• Allow All Registered Users: when set to Yes then any member of the BP community can become a registered user at the default role on that blog. When set to No the Community Blogs plugin becomes a Group Blogs plugin.
• Groups To Allow Access: is a list of the BuddyPress Groups that can become registered users. More that one group can be given access if you like. The group slugs are used to specify what groups have immediate registration access to the blog. This allows blog admins to configure the plugin without the Site Admin having to give them group ids. If the blog admin can find the group slug they can configure access.
