Back when I'm still not very good on making websites I tried to create a website for fun using a free hosting service, and I decided to make some sort of game walkthrough website (the website is really, really simple) and I decided to name the site "gamehelp" (it's not really creative, eh?). The 16 is from the site url which is actually a subdomain of "net16.net" (I'm using free (sub)domain provided by the web hosting site)

I hope I explained this well

Also I have made a few (not really good :p) incremental games:

http://gamehelp16.github.io/thegoldfactory/

http://gamehelp16.github.io/chickens/

You have a number too! :D

Thanks for the detailed reply!

What does it mean when there is a ".username" at the end of the tag?

Hi, thanks for the answer! :D
