I installed Windrop 1.8 using the .exe I downloaded from the Windrop site.
The script I want to use has "package require tls" so I downloaded "tls1.6-win64.zip" from: http://sourceforge.net/projects/tls/files/tls/1.6/
In my eggdrop.conf, I loaded tls.tcl successfully, but the script still says I don't have tls. I am guessing that I need to install TLS on my computer, separate from Windrop.
