datlechin Thank you for your reply. But I mean that if I use the bbcode in the code tag like [LIKE] Interesting content [/LIKE] to introduce this bbcode to user, then the whole [LIKE] Interesting content [/LIKE] will be hidden. If the user like the post, only Interesting content is shown, so they cannot know what the bbcode that I used.
I have to use [like] [/like] instead to introduce users about this bbcode, with a note that they have to use them in the CAPITAL form to make it work.
Anyway, thank you for your hard works. I am using about 8 of your extensions for my site, all of them are great.
