You have to reach level 2 to add clickable links in yahoo answers. Basically, concentrate on other questions and other categories also with which you are familiar. Then in a day add one or two answers with IRC page links. It is advisable not to keep giving IRC page links for all the answers you make in a day. You might be banned from yahoo answers for spamming and it could get IRC also into trouble.
So keep a watch in what you are doing.
