As of early June, 2000, the massive collaborative project support site at SourceForge [http://sourceforge.net/]/[https://sourceforge.net/] has (at least) 55 projects in (or using) Tcl and Tcl/Tk.  Some stay in the top downloads, or high-activity category.  This page is started because ''so many'' projects have been moving to SF.

Browse these projects from their trove list at:
     http://sourceforge.net/softwaremap/trove_list.php?form_cat=182

Free to OpenSource developers, and development collaborators, SourceForge provides:
 
   * Apache/PHP web support with CGIs
   * SSH based shell access
   * FreeBSD and multi-version Linux compile resources
   * Web and mailing list feedback/discussions
   * CVS repository with SSH-based update, public access and CVSweb
   * High speed FTP and HTTP download sites
