I need 2 automate certain set of tasks I perform on a regular basis. For example, everyday I need 2 browse through all the forums & threads on a site (say, this one) and find all the messages posted last 24h and containing a phrase, say, "hi everyone" (in fact, there will be a set of such phrases). At least, I'd like 2 have all of them in the list. One may say that I'd use the search option in this forum, but this is the case that this option doesn't work nice on that site the way I want it to. For my best, I'd like 2 reply automatically to each of such posts with "<sender's name>, read the rules before u post". That is, I need 2 locate & insert his name. How would I do it without creation of special software that is programmed 2 do it (just like MS Word which is capable of finding all occurrences of a phrase, "search&replace") ? I've heard about add-ons for firefox - is there the one that can do it ? Or, can I write a script and run it, say, each night ?
