Okay... So everybody heard about presentation. You know that thing that makes university lectures a little bit more exciting...

I guess you know even better what I'm talking about.

So today I'd like  to present (heh) you some helpful creation and stock services that might be useful while dealing with presentations.

Here they are:

It speaks for itself, doesn't it? 

Not the best example but nevertheless:

And finally https://docs.google.com/presentation

I guess every active Google user heard about this cool service. Among the undeniable advantages are a great variety of tools, online-sharing and file-converrting. Enjoy!

And here is the small example of the same presentation below:

Good night!

A little bit about learning new words

https://www.wordnik.com

Have you ever heard about the service?

Just a great tool to enrich your vocabulary!

What's so special about it? 
It's accurately designed service which provides you with not only some new words (can be sent on your e-mail) but with all the aspects concerning the material (definitions, etymology, related words/phrases, visuals and even the popularity of the words among the users). The site is divided into three parts which represent different aspects of the service. It's really easy to use.
It also has the active online coomunity of learners from all around the globe. So ypu may join them right now to start a new way of learning English! 
Good luck!
