I have a few GMail accounts as I get various emails from all sorts of places. One account I use for allsorts, such as joining forums and the like. I then forward the emails to my main account. Anyway, I stopped getting emails that were forwarded which I realised the other day, and I just noticed it again now, so I logged in and it redirected me to a page saying my account was disabled. Odd. It really sucks because there's some important stuff on it. It has made me realise though that they can cut access to any account at any time... if they cut my main account I'd be screwed.
So just a warning, be careful with free email hosts. I thought I'd be safe with Google, but no. I've requested they look into it, maybe it was a mistake but it is causing me hassle.
