Forum:How does this forum work?

Yesterday I checked most of the topics in this forum. Today I have all topics marks unread. Is there a reason for this?

Also, why some of the threads are bold with the dialog box and some not? 16:34, August 24, 2011 (UTC)


 * I am not sure about the first part, but ones that are not bold have not been edited for a certain amount of time. I am not sure the time before they "un-bold".  DaRanger  |  Talk to Me  |   What I've Done  | 16:48,8/24/2011


 * Bold threads are the unvisited ones. However, I believe Chrome and Safari will not let you set anything other than color for, for some baseless security reason. I'm not quite sure what the mechanic is for the ones that are unbolded, depending on the browser it seems to change at will.


 * Ah, I should have said I'm using Firefox 6.0 and that I have CSS to change the color of the visited links a:visited {color:purple;}
 * The explanation about bold/non bold makes sense, the ones older than 7 days are not bold.
 * But the annoying part is the other one, the pages sometimes are shown as not visited; this happens once in a while and forces me to open a lot of links that I've read, even the history shows no change in the page.
