When logging in, you might be prompted to verify the account; if so, enter your cell number to get a verification e-mail or phone call.
Once verified, you'll have to agree to the terms of service; do that, and click continue.

An ongoing project to catalogue all of these sneaky, hidden, bleeding edge selectors as I prepare my JSConf EU 2012 talk.
Everything is broken up by tag, but within each the selectors aren't particularly ordered.
I have not tested/verified all of these. Have I missed some or got it wrong? Let me know. - A
A friendly reminder that you may need to set this property on your target/selected element to get the styling results you want:
-webkit-appearance:none;
Choose: Tools > New Plugin
Paste in the contents of "timestamp.py" below
Save as timestamp.py in ~/Library/Application Support/Sublime Text 2/Packages/User/ (should be the default directory that pops up when you save)
Choose: Sublime Text 2 > Preferences > Key Bindings - User
Add:
{ "keys": ["super+ctrl+t"], "command": "timestamp" }
To make command+ctrl+t perform the insertion.
Make sure to add a comma after the previous keymap entry, if present.
