Our way, here at the monastery, is to select "comment on", and put comments where everybody can see them (and mod them up or down, as appropriate).
I think you are getting into needless complication with the files. When I write webcrawlers, I usualy use an array to hold URLs I have yet to download (push them in at the end, shift them off the front end), and a hash to tell me which URLs I've already pushed into the array (NOT the ones I've already downloaded: why have multiple copies of the same URL in the array?).
Of course, your first question would be, what happens when that array and that has become really, really big (which can happen quite easily on the internet). And the answer is: When that happens, you can either use DB_File to tie both the array and the hash, or you can use a real database. | [reply] [Watch: Dir/Any] |
