Use Captcha images:
Use a graphical captcha instead of a text captcha (only if your PHP has GD support).
The font of the graphical captcha can be changed by simply downloading truetype fonts from the Internet and copying them into the forum's /images/fonts directory.
In addition to this, one can define captcha plugins to create a custom captcha for your site. For example, you may want to ask for a registration code, your gang's secret password or use a mathematical captha.
We've also included a RECAPTCH plugin with the forum for users that wants to use the recaptcha service or just as an example of how easy it is to code such plugins.

1)
is here a way to show captcha test on a message submit or a reply?
it seems like some people register by hand and then -- auto-login and spread the spam (
2)
can i implement a way to auto-test browser by JS without asking user? it's something like anti-captcha (see blog.fili.nl/articles/the-anti-captcha-challenge/ )
i don't want to ask user "Please enter the code shown below" it should be parsed automatically.

The forum can already show captchas for anon posting (if enabled). It won't be too difficult to change the condition to show it every time.

The next release will also be able to queue a user's first N posts for approval. For more spam prevention tips, see Fighting spam.

Sure, write a plugin, make the challenge field hidden and add some JS to auto fill the field.

I just installed FUDforum (MUCH better than phpBB. So much so, it's not even funny). It seems like the graphical captcha option doesn't work even with gd compiled into PHP. When I registered on fudforum.org just now, I see that these forums don't use the graphical captcha option.
Did I miss something? Is the graphical captcha supposed to work?]]>audiodef2011-08-10T14:35:09-00:00Re: Enhanced captcha's

Yes, to both. Is there something else I could have missed?
Not that I can think of off hand! I just tried switching the captcha on and off through the ACP and had no problems on 2 different installations so it should be available for you.
When I registered on fudforum.org just now, I see that these forums don't use the graphical captcha option.
GD is disabled on this site, that's why you see the text captcha here.
If GD is enabled (check with php_info), and graphical captcha is enabled in the Global Settings Manager, you should see it on your forum.

I'm think I should file a bug report, unless someone knows about something else I need to check.
System info:
FUDforum version: 3.0.2

Please enable PHP error logging to trap it.
