First, leave some way they can contact you (irc, xfore, etc...).
Second, please donĀ“t use this red leters.
Third, hardly any clans will approach you through forum, get irc (chat program), hang around there and after you get to know people and play with them, ask em for tryout.
Another option is to be really good in pubs, maybe someone will aproach you then.
Edit: btw, please rename your topic. As I understood you needed help for your clan, not for you to get into one.
This could also be usefull:
