kamailio.org uses an invalid security certificate.
The certificate is not trusted because no issuer chain was provided.
(Error code: sec_error_unknown_issuer)

Hello,<br>
<br>
as of yesterday, creation of new accounts for Kamailio's wiki site<br>
requires to answer a project related question. Captcha was useless as<br>
spam bots were lately going through it easily, creating accounts in a<br>
rate of approx 50 new registrations per day.<br>
<br>
The extra question is asked just after CAPTCHA, see it at:<br>
- <a href=3D"https://www.kamailio.org/wiki/start?do=3Dregister" target=3D"_=
blank">https://www.kamailio.org/wiki/<u></u>start?do=3Dregister</a><br>
<br>
Hopefully the questions are simple enough to allow good people to<br>
register and difficult enough for spambots to give up. It is not a very<br>
sophisticated system, let's see if there will be any efforts in reverse=
<br>
engineering to break in with bots. So far no new spammer account. If<br>
they will succeed, at least they learn something useful.<br>
<br>
If anyone has difficulties creating wiki accounts, write an email to<br>
sr-dev mailing list and it will be investigated.<br>
<br>
Cheers,<br>
