A easy way ist to do this:
Type out what your link will say (for example "THIS!"
Then copy the whole URL of the address you are linking to - http://gamesas.com/en-us/community
Highlight what you typed out before that you want to be you link - THIS!
Then look at the second bar at the top of your post window, look next to the "list" function that has the 123 and you'll see a chain "link" with a green dot on it. Click that.
Now a small window will pop up, paste the URL you copied into the URL field and then click OK
Now you can click on http://gamesas.com/en-us/community
Highlight the thing you wanted to link then click the Chain-looking emblem with a green box in the bottom right at the top of the text box and add the URL to the box that pops up.
Edit: http://www.bethblog.com/ [Should go to Bethblog.com]
Edit 2: Just noticed how confusing by directions might have been with all the ' top rights' 'tops' 'bottoms' were. Highlight the text you want and afterward with the text still highlighted, click the chain with a small green box at the bottom right of it. This chain is at the top of the text box you type in right under the "Size drop down box".

Start with
[url=.
Then add a copied link in there (the full link with the HTTP's and WWWs).
Then close it off with a
].
Now enter your text that will be seen as the link such as "Click Me".
Now finish is off with

EDIT: Wow, the forum software is getting really bad with formatting errors everywhere.
Also you can just paste a full link here and the forum will automagically format the link to be click-able, though it won't have any custom text to it.
It should be (without spaces),
