InfoPath Dev

 How can I find out if infopath forms services is being used on our sharepoint site or if it has been activated ?

Do you have access to the SharePoint admin side? If so, you should see a section for configuring InfoPath Forms Services there.

If you don't have access, then try publishing a browser enabled form. I believe that if IPFS is not present, you might get a warning while publishing.

Thanks for the feedback , Ernesto These forms are on a subsite and I am the owner of the main site as well as the subsite? What do you mean the admin side? Do I need to install something on my computer to have this development or admin rights? Also..how do you browser enable a form?

The SharePoint admin site lies on a separate port.

You don't need to install anything on your computer. Everything is done via IE. 

This article explains the compatibility options, the design checker, and the publishing or forms. Hope it helps to clarify things.

 I have full control of the site now. I was able to publish browser-enabled template. Can this kind of template when published be made accessible to clients who do not have access to the Sharepoint site?
