Suggestion:

Currently, when someone posts a link in a thread such as this, it displays as black text, meaning that unless you hover your mouse over the linked text, you could totally miss the hyperlink.

I think currently, the only way it gets displayed in color is if you have already visited the linked site recently. Even as I type this, the text I linked is colored pink. But I know after I submit this post, it will return to grey because I have already visited the site. If I didn't, it would appear as normal text.

Or maybe it's my browser?

 When I receive the post as an e-mail alert the link is colored blue, FSeven.

Weird...I still have to pay more attention to see if there's a specific pattern.

For example, check out this picture. Now unless you hovered your mouse over the (CDT) text, you can't tell it's a hyperlink. It looks like regular text.

When I receive the e-mail alerts, they are colored as well, but not in the post itself.

 I use both Internet Explorer and Firefox browsers and you are correct, FSeven: there is no coloring to the hyperlinks. If you wish to call more attention to the links you could always italicize them (I do).
