Greetings, I am working on compiling a comprehensive list of online
resources on a specific topic. I am not looking for content or links.
I am looking for a PROGRAM that would allow one easily assemble
hundreds (or thousands) of links into dozens of sub-catagories. It
would be nice if such a program worked on the web, so the general
public could submit URLs as well. [For a simple example I am currently
using take a look at http://herpetology.com/webdata.hts ]It is written
in Miva but editing the database is very difficult.  I would like to
be able to EASILY delete the ones I do not like. It would also be nice
if links could be rated by the public and rankings on specific URLs
displayed. An automatic link checker for dead links would also be
required. I've seen these features on the net. Surely there is a
commercial or shareware product out there for this. Please advise. I
do not have a budget for a custom developed tool, so please do not
suggest that. If what I want runs on the server-side, please include
details of what I would need from a domain host. Thank you.

you can try this one:

Powermarks 3

function:
Powermarks allows users to avoid the entire folder and hierarchy
system, yet still create, find, and browse large collections of
bookmarks. Powermarks works with all the popular browsers: Netscape,
IE, Mozilla, Opera, and NetCaptor. It includes notes, descriptions,
and keyword fields for each bookmark. It has flexible import and
export capabilities, synchronization with browser bookmarks, autosave,
undo, macro, copy and paste, and global hot key features. It also has
intelligent Web page status checking, proxy and HTTP 1.1 support, and
more. In addition to the IE toolbar, this update includes two
configurable system tray icons to enable easy integration with
Netscape, Opera, NetCaptor, and Mozilla.

Interesting program, I like the link checker. It doesn't allow
collaborative URL submission from other web users, however.
 
Thanks for the suggestion.
