Is your site on WordPress.COM? If so, you cannot use plugins on WordPress.COM sites:
http://en.support.wordpress.com/plugins/
yes it is but I was using it last year. Did they change it or is it in another version of wordpress?
No, it’s never been possible to use plugins there. On the self-hosted version of WP (which is what this site and these forums are for), you can use plugins – perhaps this will be helpful:

For WordPress.COM support, you’ll need to use their forums, BTW. [But don’t bother asking about plugins :).]
I’m so confused…. I wasn’t building the site on ww.wp.xz.cn. Doesn’t even look like one could build a site on wordress.org. That site just gives me downloads for themes, pluggins and things like that. I was building my site on wordpress.com and in the area with all my tools pluggins was one of the options because I had added the pluggin buddypress to my site. I am obviously missing something or something has definitely changed.
No, you cannot build a site here – no one can. ww.wp.xz.cn does not host sites. You’d need to pay for hosting from a hosting company.
Where is your other site hosted? i.e. who are you paying?
This is what I am trying to do, I am trying to build a social networking site on wordpress.com and I am trying to add buddypress back onto my site. How can i achieve these goals? Or do I need to go back to Joomla, however joomla seems to be much harder than wordpress that’s why I started using wordpress last year.
You CANNOT do that on WordPress.COM, no. You CAN do that if you set up a new site on a independent hosting company. See:
https://ww.wp.xz.cn/hosting/
No reason you can’t do it with WordPress, just not on WordPress.COM – which is totally different than a self-hosted ww.wp.xz.cn site on a hosting company.
