a. KICK BLAZEFAN OUT! Damn hes annoying. The only thing ive ever heard Blazefan say is'OMG' and 'Blaze'. No offence.
b. Regular (weekly) backups. I use my own website theme, and I dont know if you can back up free ones, but I back everything up on drivehq backup. Try it.
drivehq.com. I'm not obsessed, I'm helpful.
