D6 modules that deserve some thanks...
Recent roll out of a website meant hunting about for some quick fixes in a hurry. A few lightweight and very easy to use Drupal modules made my list for "Worth mentioning and giving some thanks".
String Overrides by Rob Loach - String overrides is great for quickly replacing text that is displayed by default by Drupal Core.. at least, that was my use case. I'm sure it can also be used to change various strings on the site and can serve as a good backup if you're making major changes and are unsure as to how often a particular specific string of text shows up.
External Links by quicksketch - I needed a way to get RSS feeds to open to a new page (especially since the content would take you away from our site). This module was quick and easy to install. You also can enable/disable icons which will show you when there is an email address or an external link.
