I log into this site using the search button and then log in. The fields are filled in and then I read the forum. So often I go to reply to a poster and then press preview and it loops me back to the list of forums. Any help is appreciated.
The website is having issues that they are working on; it has to do with keeping you logged in if I understand it correctly. I switched to IE (instead of Firefox) to post and didn't have the problem.
The site is having problems but I'm curious as to why you're using the search button to log in? At the very top of the page is 'Log in' and if you click the box that says 'save information to this computer' you won't have to log in each time you return to the forum.
