If you want to create a "proper" link in a post, rather than just paste the raw URL, it's very easy to do.
Before
you can insert a link into a post, you'll need to copy it from
somewhere. There are a couple of ways to grab links in Firefox and
Internet Explorer:
Copying the URL from the Address Bar by highlighting the address and right-clicking on it
Copying the URL by right clicking on a link in a page in Internet Explorer

Copying the URL by right clicking on a link in a page in Mozilla Firefox
