Tcl-based editor. Runs on Windows, Unix and MacOS, using Tcl/Tk 8.1.1 or newer. Maintained by Vince Darley.
Alphatk has had the ability to browse remote Wiki's (using the http package) for quite some time. Recently, it added the ability to edit pages on those Wiki's --- this means you are no longer limited by your browser's very poor text editing frames. When you click on the 'edit' link, Alphatk opens up the Wiki markup in a temporary window, and when you save the window, it is http-posted back to the Wiki it came from! See How to edit Wiki pages in Alphatk for details. Similarly you can use Alphatk to edit TIPs, and ftp sites remotely.

Any constructive comments and criticism on Alphatk is much appreciated. But please say what platform/window manager you are running on!
