I can very much use a script that does this to a text file but i don't know any programming language so if you be so kind as to write this thing for me and explain to me how to use it, i will appreciate it very much!
1.find an email address that is in a line that doesn't begin with "EMAIL"
2. if the first letter before the email is anything other then ":" and/or the email isn't the last thing in that line - stop and i want to see that line
3. replace everything in that line before the address with "EMAIL:"
4. repeat
