SPBasePermissions enumeration - values in Int64, Hexadecimal, and Name

$t = [type]'Microsoft.SharePoint.SPBasePermissions'
[enum]::GetValues($t) | ForEach-Object {Write-Host "$($_): $([int64]$_) (0x$([Convert]::ToString([int64]$_,16)))"}

Haven't figured out a way to use Format-Table for this, but good enough for now.

SP2013Beta: Adding site (SPWeb) users

I ran into a several relatively trivial issues with adding users to the Members and Owners groups in SharePoint 2013 Beta

My administrator user does not have a Site Settings option under the gear icon at the My Site. However, this was available under my Home site ("/"), so doing some URL mangling, I was able to get the My Site Permissions page by going to /my/_layouts/15/user.aspx

Note that "All Authenticated Users" is now called "Everyone"

The people picker doesn't look like it's working. I get a "Sorry, we're having trouble reaching the server". However, I am able to add users (ie: Share, in SP2013 speak) if I enter the complete name in the picker.

Finally, the "Send an email invitation" setting is checked by default and only accessible after you expand Show Options. That is annoying.
