Depends on the "super power" really. If I had lame ass powers like Aquaman, I don't see how you even could use them to help humanity by much. You could however put on one badass show at seaworld where sharks do flips while giving rides to sea otters and a giant squid juggles motorcycles. Aquaman could be getting mad money, yo.
I think I'd end up being lazy and just using propane tanks and Molotov cocktails, very little preparation needed, and you could set an entire horde ablaze quick and easy. Then of course after they've been burning for a few minutes and the smoke starts to gather you'd either need an escape plan or a gas mask/respirator.
Step 1: Make explosives Step 2: Air Horn Step 3: Profit
Like eveyone else has pointed out, it just depends on the specific scenario, but even the smartest zombies usually can only open doors or have the predatory instinct to hide; they're all still pretty stupid and wouldn't recognize a bomb if they were shambling on top of it.
There should be a button at the top of the page that says 'Notify' and I think that'll shoot you an e-mail when someone posts in the thread(not entirely sure because I've never used it before). If you have your iphone setup to alert you to new e-mails though that pretty much works the same...kou could even get a bit fancier I think and set up a seperate e-mail if you wanted just for game updates...kind of a hassle though. Personally I'd just set a bookmark to the page or something and make a mental note to just refresh every now and then.
