It's probably better to purge them entirely if you don't need them any more.

In v 5,1 though you will be able to hide blogs from the backoffice menu.

Thanks for getting back with me. What would be the best method to purge them?

Let's say blogs 3 and 5 are old, they are purged. Can those blog numbers get used/reassigned again with a new blogger?

In blogs > all there is an icon to delete a blog.

You can't reuse the ID once the blog is deleted unless you do some heavy tweaking of the database, which I strongly advise you should NOT do.

Okay, thanks! :)

hi, just installed v_5.0.0. Whatever happened to the option in the blog's features tab in the "List of public blogs"?

Include in public blog list: [check box] Check this if you want this blog to be advertised in the list of all public blogs on this system

I want to keep three of the new blogs for later use, I don't want to delete them, just don't list them.

Is there a way to do this in this b2evo version? Like, what/which file/s could I modify if there is no longer such an option?

TXs!

The option is still there, but it has moved here:
