[wp-hackers] But only in the posts I want

[Mário Gamito]

Hi,

I'm developing a plugin to display a button to a Portuguese bookmark 
service. It's already runninng  well, it appears on all the posts.

But what I'd really like is to have in the write article page near the 
editor a checkbox so users can select only the posts they want to have 
the button.

How can I achieve this ?

Any help would be appreciated.

Warm Regards,
Mário Gamito
