What bugs me is that if I make such an underlined link, it works fine, but if I go into my post later to edit something, the link changes. Extra text is added at the "a href=" part.
Yes, you are doing something wrong. Check the placement of your quotes very carefully against the example I gave in the link in my previous post. Also, check very carefull where you place the angle brackets. Finally, make sure you don't forget to the put the </a> at the end.
Write your text directly in the Forum window. I have had problems when I have written text in Word and pasted it to the forum. The " didn't turn out right, making the link unusable (adding sonysomething at the beginning of it).

Generally the quotes aren't required in hyperlinks unless you have spaces in the URL ... and you really should never put spaces in URLs. Use underscore characters instead. Then you can leave out the quotes completely.
This will work fine, and you should be able to edit it. You can copy the above line directly from this message and copy it into your own post and verify that it works, and can be edited.
Here is what the above produces, and I have gone back, using the Edit button in this forum, and verified that the coding is still intact.
I don't know why the target=_top is being put in there, but it shouldn't be a problem. That causes the link to open in the top level window if it is inside a frame. If the page isn't in a frame (and SONY forums don't use frames) then it will have absolutely no effect at all. Does the link still work if you leave it like that?
Just now I went back inside my first post and copied the altered contents. Here is how it now comes out (you'll see that the hyperlink is all screwed up and no longer works):

Okay, here is a link to <a target=_top href="http://mediasoftware.sonypictures.com/default.asp ">Sony.
The link is still exactly the same, as far as i can see. The only thing that has been added is the "target=_top" part, which shouldn't affect anything. You could just delete that part if you wish when editing.
