I'm trying to solve the following scenario: - the list is public - the list has archives - posters routinely reference previous postings using the URL they get from either searching or in the daily digest - each month I want to edit the postings to munge email addresses to protect them from spambots crawling the archives looking for them - I may further want to trim some postings (e.g. remove footers) or even delete some postings Q: will the URLs survive the notepad edits? Note that I'm not re-ordering the messages, but their length may change. Q: Or, restating the above question, perhaps, what do the parameters to the following url mean: http://lists.mydom.com/cgi-bin/wa?A2=ind0206&L=mylist&D=1&H=1&O=D&P=1409 I'm guessing that: A2 = the notepad file name, i.e. the archive month/year L = listname The others are a mystery to me, though it seems that P is the only important one. If I mess with the message lengths in the archive 'notepad', does P change in value? In short, what is P and will it stop me doing what I need? Is it a line offset into the notepad file so as long as I don't delete lines I'm ok, or a byte offset (I hope not!). Or ??? Any suggestions or comments gratefully received (e.g., perhaps I don't need to worry about crawlers in the first place as listserv will automatically throttle and/or otherwise defeat searches by crawlers?). I've been back and forth through the archives and found lots of good tips, but no definitive answers. thx! michael
