Does OACS include something like BooHoo [http://greenspun.com/boohoo/index.tcl] in order to keep a record of dead links, or be promptly informed at least?
I guess it would be something useful and, quoting straight from the linked page, "the software is pretty simple".

there is code in the bookmarks module to check if the links are dead but it does all the links in the db not for a particular user.
