There are two different URLs that relate to the recent posts page. There is the search string from the link at the top of the page and there is the results of that search that will be in the address bar once you go to that page.
The first looks like
Code:
http://ecomodder.com/forum/search.php?do=getdaily&days=2
The second looks like
Code:
http://ecomodder.com/forum/search.php?searchid=xxxxxxxx
where the "x" are numbers that will change every time.
If you bookmark the results it will error out. If you bookmark the link it will work as expected.
