Bukkit

NoCheatPlus has a function which allows captcha introducing when flooding. I personally like to combine this function together with ChatGuard's own flooding control.

But it seems that another of ChatGuard's functions: caps percentage, is conflicting with the NCP captcha, which sometimes asks for the introduction of up to 6 characters which may all be caps. When this happens, the player cannot answer.

It is strange however, as sometimes the message only contains up to 4 caps, the rest being small letters, and the captcha cannot be introduces correctly anyway, which makes me think the minimum message length feature present in the same caps control section may be malfunctioning.

Thanks again!
