Due to a mishap on the site, some of the setting got messed up.
If you wish to be able to post external links on your posts you must take the following steps.
1)Click on Profile
2)Click on Preferences
3) Scroll to where it says Always have HTML On (or something similar) and then click yes.
4)Save your settings.
That is all. I cannot do it for you, thus you must do it yourself.
P.S. You will also see that on the bottom right of your screen you will see a little red box that says chatbox. For those of you who dont know this is a pop-up chatbox, which allows to use the chatbox while browsing the forum. So for instance I can be writing this part right now while viewing the chatbox. You can all thank Mirasi for recommending this feature.
