Yay, hopefully Adrian will be the next spouse! I am glad you almost got all your requirements done too! To answer your question, all you do is press the hyperlink button (globe with paper on top) and this pops up:
[url*][/url]
Then get the address you want the link to go to and copy and paste
with an equal sign in front, like this:
[url*=http://www.carls-sims-3-guide.com/forum/index.php/topic,74.0.html][/url]
Lastly, add in the word you want the link to be represented by in between the brackets:
[url*=http://www.carls-sims-3-guide.com/forum/index.php/topic,74.0.html]Forum rules[/url]
And that becomes this (without the asterisks, those were just examples):
Forum rulesSorry, that was off-topic!
Oh yeah and happy birthday Agnes!
