I will be about but im doing something with Afterlife in WvW ;-) but I won't be on until 11pm anyways.
If you're planning on WvW at reset Git go to Lion's Arch and stand at the portal for the map you want to join.
Start spamming the 'F' key to enter the map the instant the score resets to zero. You will get a text box and your screen will go black. Ignore the text box and don't worry about the black screen. Just keep spamming 'F'. 100% success rate.
It works from the overflow map but you obviously need to know which portal to stand next to and you can't see the score resetting so you need to be told when to start spamming in TS.
If you use the press 'B' for WvW screen the click on join and choose map you've prolly got a 25% chance at best of getting into the map at reset.
