SSID-based SMTP server changer for Evolution is a simple script that uses gconf and NetworkManager (via D-Bus) to check which wireless network (SSID) you are currently connected to, and updates Evolution's accounts list (in gconf) to point to the correct SMTP server for that network. It is useful for when roaming between wireless networks that are connected to different ISPs.
Numerology Widget is a simple to use tool for numerological analysis. Numerological analysis is not limited only to personal names and birthdays. It can also be used for the analysis of a company name, date of the establishment of a company, the name and date of a special event or occasion, etc. Numerology Widget features name numerology, calculation of key and subkey for a given date, description of basic and compound numbers (up to number 52), automatic matching/harmony analysis between keys and names, a table of matching/harmonic numbers, and full numerological reports that can be emailed or printed.
Spam Trainer makes it easier for GNOME users to train spam filtering software (e.g. SpamBayes or SpamAssassin) that "learns" how to tell the difference between real email (ham) and unsolicited messages (spam). Not all email clients have spam filtering (and training) built in, and training external filtering programs can be fiddly. Spam Trainer provides easy (drag and drop) training from the Evolution mail client, and should work just as well with any email client that supports the drag and drop protocol implemented by the GTK+ toolkit.
