The way it works is that new users still see the box to add their signature in their member profile - but the length of signature allowed is 0 until a member has 30 posts. This is to prevent people from signing up just to get links on the board or links in the board's database.

Thanks for your answer.
I fully understand that, I run two article directories (one is dedicated to real estate) and I get many spam trials as well.

One question though, after a member reach to 30 posts. Will the signature be shown on the previous posts as well?

Yes

Thanks for the quick (and wished) answer

I am using the bbcode as it states in the FAQ section, but for some reason it is still showing the link each time. So I just removed it for now. Any suggestions???

Now that you have 30 posts BB code should work in your signature as long as it is entered correctly. I don't believe the forum will accept html in the signature field.

Thanks I will try again. I already had 30 post when I was attempting to add it, so I don't think that was the problem.

If you continue to have a problem just send me the code you are using in a Private Message and I will check it out.
