SourceForge http://www.sf.net/ - aka SF - is an ambitious attempt to provide open source projects with freely available source code , bug, and request management facilities, mailing list support, compile farm access, software distribution, and more.
The effort has over 324,000 projects at this time (2013-08-31).
Free to OpenSource developers, and development collaborators, SourceForge provides:
APN 2013-08-31 The list below is hopelessly out of date. Your are better off going to SourceForge Tcl directory
GWL 2013-09-01 Please note that the main repository of the Tcl/Tk project (as well as those marked with an asterisk "*") is on http://core.tcl.tk as Fossil[L1 ] repositories.
But rather than advertising SourceForge here, go browse the projects, or start your own, and announce it below:

etc.
There is also a small code snippets library there:

You may not agree with them, but they mention some reasonable points.
DKF: IMHO, SF sucks. But it is really nice that they are providing/handling all the sysadmin/hardware side of things, so I guess it doesn't suck too much.
Where in all of SF does one find the tclconfig module that so many TEA based extensions needs?
AK: It is not a module, but a subdirectory in the module 'sampleextension' in the project 'tcl'.
