I have added some DLE/WP/Xenofero CMS based site, but all of them failed most of time,
Need to add custom selectors to leech works.
Now, I ask how can we make selectors ourself?
Thanks.

You probably meant leeching, because adding can't really fail, I don't check for anything, it will always add.

You can add custom selectors yourself. They are explained in the FAQ: http://leecher.freddy.lt/faq.php (but you must have some HTML knowledge)

The blogs just have a lot of themes, most of the time each blog has unique theme, so it's not possible to make them all work at once. But you can add selectors and they will work fine.

ok, but as i Don't know HTML, how can I find selectors?
I send mail to give me custom selectors of those sites, but you don't reply any mail.
thanks.

I don't really have any unanswered emails. They might have gone to my spam folder for some unknown reason. Will take a look.
