TextExpander, a $29.95US utility which inserts snippets of text or images when you type a preset string of characters, has long been a TUAW favorite. I only recently learned that it can run AppleScripts within a snippet, which opened up a world of fun for me. Here's a quick script demonstrating how AppleScript can be used to randomize quotes within your email signature.

Create a new TextExpander snippet and set the content type to "AppleScript." Copy and paste the code that follows into the snippet content box. I'll run through what it does in at the end.

Read on for the script!

All the way since back when I started using a Mac, the program that's been most recommended to new Mac users in my experience isn't Adium, Transmit, or Quicksilver (although those are certain all terrific apps/reasons to be a Mac owner) -- Cocktail is the one that I've seen on the Top 10 Mac apps most often. And there's no question that while Adium and those other apps might be flashier or more UI-driven, Cocktail is the nitro you toss in your car's fuel line to supercharge all of the stuff under the hood. From disk repairs and standard maintenance, to network optimization and cache and log file clearing, Cocktail is exactly the kind of program you buy a Mac for -- it gives you control over almost everything going on in your computer.

They've just updated to 4.1.4, with a whole slew of optimizations to show for it -- the application itself has shrunk in size by 50%, and there are lots of upgrades for faster and more reliable performance. Additionally, compatibility with FAT32 volumes have been addressed, and they've upgraded Automator actions, so they've given you even more ways to control everything you've got.

Great app, well worth the $14.95 for a single-user license. All the other signature Mac apps will let you do your daily tasks in style and with a little flair, but Cocktail is the one that will help you do them quickly and cleanly.

I'll have to agree with Dvorak that mail apps that don't allow HTML are lame lame lame. Apple's Mail will allow you to see HTML emails, but not compose them. I guess that's supposed to be a security/annoyance feature, but sometimes I would really like to make an HTML email... But at least we can have CSS for our signatures.

CSS, for those who don't know, is a way of styling web pages. It's more precise than plain ol' HTML, and quite frankly, more powerful and better looking. My personal site uses CSS exclusively (much to the chagrin of Netscape Navigator 4.7). Anyway, Melvin Rivera has a step-by-step tutorial on using CSS in your Mail.app signatures. You may want to learn a little CSS first, if you've never tried it before. Just like using a Mac, you may never go back.

Other Signature X is an applescript for Entourage 2004 that will allow you to assign signatures based on the recipient or group you're sending a message to. While I don't use Entourage myself and can't test this, it sounds like a great idea that I hope gets adopted by email apps in general. You can pick up the script from the developer's iDisk under the directory "Entourage X-2004 Scripts," while I found it at ScriptBuilders. If anyone tries this out, please let us know what you think in the comments.
