How to add captcha-support to a plugin?

[dma147]

Hello all...

I'm just writing this discussion forum plugin and I want to provide captcha-support for posting new threads or replying to threads.

I've searched the whole source of s9y but I can't find any examples on how to add the captcha-support of the spamblock plugin to my plugin.
I've also tried to find out how this is done with the comments in the entries of s9y, but I can't find anything about this.

Does anybody know how to do this?
So please tell me here.

Thanks.

Alex

I suggest to look at the "serendipity_event_contactform" plugin. This hooks captchas.

thanks garvin...
okay, I've got it to work...

Now the discussion forum also makes use of spamblock (captchas), which is surely configurable by the admin.
