Not everyone can do this, but just a thought to pass along. I've been leaving my spare computer logged in as often as I can, and parking one of my heroes on the steps of City Hall in Atlas Park. I prefer the symbolism of
/emote HoldTorch
I'm starting to notice a LOT of tells every day when I get home from work, apparently Winchester has been noticed and is drawing support. Kicking myself that I didn't think of this earlier. I added the following to his "uniform" for this duty:
/afk Vigil to help Save COH tinyurl.com/SaveParagon
That allows him to explain what is going on even if I am not at the keyboard, and also gives some gamers who seldom read forums or gaming websites a simple, easy to remember link to get here. I've got Protector covered, and can switch the same hero to any server except Exalted. Occurs to me it might be worth trying to get at least one hero standing on each server advertising via AFK by their silent presence.
Also worth mentioning that I have seen several other heroes stand vigil, too. The idea is definitely getting out there.
(edit to add in the following from further down in the thread - a suggested "Vigil" macro")
/macro VIGIL "maxinactivefps 1$$e HoldTorch$$afk - Vigil to help Save COH - Titan.SaveCOH.com"
You can if you wish substitute any website you wish, I'd suggest whichever of the redirects from this thread catches your fancy. The dashes and spaces are there to get the AFK banner to break into two lines.
