maybe it fixes up your problem. goto-->start-->run-->type "cmd"
now in command prompt, type
"ipconfig /flushdns"
clear all your browser cache, cookies etc. restart your computer.
for the forum address, go to www.apnicommunity.com/forum and login with the "remember me mark" selected. now that should literally work. i dont see any reason why it will keep you logging out. if it still does, then go to http://apnicommunity.com/forum (without www). do the same. that is login with "remember me mark" selected. then start browsing.
please get back to me on this. thanks
