Okay, here's the deal. The original blank target comments plugin isn't here BUT, listed below is a puported fix of it.

~~~~~~~~~~~~~~~~installation instruction:

Plugin Name: Comment Link Target Blanker (CLTB)
Plugin URI: http://wp-plugins.net/plugin/comment-target-blank/
Description: This plugin will add target="_blank" to URLs in comments so they open in new windows. It is simply a bug-fixed clone of the most important feature of the Blank Target Comments plugin so that it can be installed and run with the otherwise mutually incompatible Link Truncator, and generates valid markup under WP2. Intended especially to be run in conjunction with the AutoLink in Posts & Excerpts plugin. Unlike BTC, it does not mess with comment author URL targets/nofollows (features of BTC that I don't find useful). Only tested on WP 2.0.
Version: 1.0b
Author: Stanton McCandlish
Author URI: http://www.McCandlishConsulting.com/INSTALLATION:
Just drop zzz-comment-target-blank.php (or its whole zzz-comment-target folder) into your plugins directory, make SURE that the Blank Target Comments plugin (wp-blank-target.php) is disabled or deleted, and enable Comment Link Target Blanker on your Plugins admin page. I recommend also installing Link Truncator and AutoLink in Posts & Excerpts. The former will do some additional smart and useful link-related stuff, and the latter will apply ALL of this great link handling to links in posts as well as comments (and even in excerpts of both posts and comments).
NOTE: This Comment Link Target Blanker plugin MUST load AFTER Link Truncator and BEFORE Autolink in Posts & Excerpts. This is why the .php file has the "zzz-..." name that it does, so that it is loaded later than the one and before the other, due to the alphabetical order. You can rename it, as long as the load order of this plugin in relation to those other two is not affected.
NOTE: CLTB is *not* compatible with the Blank Target Comments plugin, but is a replacement for it (thought not all of its functionality, some of which I found to be a little pointless in my view, nor all of it problems - I fixed a bug in it). In particular: A) It does not turn off rel="nofollow" on author links - why would you want Google indexing useless trivia about your users? B) It does not turn on target="_blank" for author links - why would you want to open links on the same site in a new window? C) it fixes a WP2.x-only bug in the original BTC code, which caused links in comments to get two rel="nofollow" attributes/values (one inserted by BTC, one by WP itself; apparently WP didn't do this in ver. 1.x, and BTC has not been updated since the release of WP2.)
IF USING WP 1.x: You will need to uncomment the line just mentioned in "C)", above.
NOTE: This has NOT been tested with Auto-hyperlink URLs
<http://www.coffee2code.com/archives/2004/07/08/plugin-auto-hyperlink-urls/>,
Shrinky Link <http://nymb.us/?p=54>, AutoHyperlink <http://journalphoenix.com/40/autohyperlink>, or MightyLinker <http://mightyhitter.com/main-page/plugins/mightylinker/>. Compatibilitity is somewhat questionable. Looking into it for version 1.1. PLEASE REPORT ANY COMPATIBILITY PROBLEMS you encounter, with any version of WP from 2.0.1 onward, and with any plugin.[eof]

I would have just combined the compatible features of both BTC and LT plugins, but their licenses are also mutually incompatible, so I've chosen to just strip BTC down to what it needs. Every line of actual code below this point was written by "Tech Wench", author of BTC. If the authors of BTC and LT want to work out compatibility between ALL of their features, I'll happily remove this kluge from distribution.
