i would like to know how to disable url in forum for members having less then 10 posts like dp has, im getting lot of spam in the forum some expert please help me thanks.
There is a mod at vbulletin.org that sets permissions to post links, send pm's, send emails e.t.c. based on the member's post count. It's highly customizable IMO and you can configure it right from your ACP. Here is the link for you to download.
Do you have a captcha? If no get one, if yes and it's the default one then change it to a custom one. If you use phpbb then move to something else, if you can't then definately follow my first piece of advice. [edit] Is it your business forum? Sorry I may have misinterperated your question. Then my earlier comment saying it wont work might be wrong. Depends what you mean by spam, automated bots?
