Multiple accounts with single email account in forums/facebook and other sites

Hi everybody, its been a long time. I was in vacation and tour and was completely away from internet for a while. I will now start to post more regularly. Anyway in this post, I will show you how you can make multiple accounts in different discussion forums, social networking sites and other different sites (and even maybe in IRCs and others) with the single email account. This trick requires a single gmail account.

I accidentally mistyped the extra dot in my gmail account while registering in one forum. But in around a minute, my gmail tab was showing 1 new message in inbox and when I checked it, it was the forum's registration message. Then I tried to find what was going on and even a quick google search revealed that this would actually work.
So the idea is just registering in your target site with multiple forms of your gmail account with dot (.) in different positions. This google answer provides the answer for this so the account coolsamar207@gmail.com would be equivalent to:
cool.samar207@gmail.com
or
coolsamar.207@gmail.com
or
coOlsamar2.07@gmail.com
etc.

This means you can register in the forums/sites with any of the above(and much more) gmail accounts and still the email confirmation would come to your email account. I mean each accounts in the site would be actually associated with the single gmail account.

I tested this with fluxbb and facebook and was working well. I guess it would work for other social networking sites like myspace, twitter, etc. This might come handy for many of you guys for different purposes. If you got any queries, feel free to ask here.
