PowerShell Candy
PowerShell is about getting work done. But that doesn't mean it has to be drab and gray. 
Sometimes it helps to add a little visual pizzazz. Like putting a border around the 
heading in a report. Or adding a dash of color to reinforce the data - without 
relying on Write-Host! In this session we'll explore the world of ANSI, special 
characters and more so that you can start adding a little flair to your PowerShell work.

Hi. I sent a message as issue to you a few months ago (to developerprofile account, I guess it yours). I have a question about a repository that you have forked. I am going to delete my github account (not this account) but you (and other users) have forked my repository. If I ask, would you delete the repository? If you reply this comment can write what repository that would you delete. Looking forward to your reply because it's important for me. Also I have contacted with Github Support too and they said me that I should direct contact with you. Thx.
