Eudora TM
The best e-mail application on the Net! Highly Recommended! Freeware Macintosh and PC versions!

WS FTP Windows 95/98/NT
A great application that allows remote file edits, chmods on UNIX boxes and file moves.

Search and Replace for Windows 95/98/NT
Searches multiple files/directories for a phrase and replaces it with another. Perfect for HTML writers who need to change links. Customizable, color coded output. Shareware & freeware downloads.

Infolink
This is a utility to easily make sure the links on your pages are still valid. You just give it the location of an HTML file, and it searches out all the links over the net and lets you know which are up and which are down. If everyone used this, dead links would be a thing of the past. This free trial version will run 50 times (not days) before expiring.
