html link works like this:
<a href="pagelinkedto.html">text for the link</a>
That code would produce:
[URL=pagelinkedto.html]text for link[/URL]
And that's it! You have the basic link! The one above goes nowhere but you can see how it works.
Now the example I gave was a way to link to a page on the same site and in the same directory. If you want to link to a different site the structure is the same but the part in the href="" would be the full URL.
Here is a link to my very first site. The Raven's Realm.
<a href="http://groups.msn.com/theravensrealm">Click here to go to The Raven's Realm</a>
That would give a link like this: Click here to go to The Raven's Realm
That's the basic structure of links in HTML.
I'll make tutorials for more options when I have time. Feel free to ask any questions.
P.S. Those links open in new windows but I did not show the code needed to do that. They will open in new windows because the forum is setup that way.
