Follow-up questions should be related to the main gist of the OP's question, not just take one word from it and create a whole new question. If you want to ask such questions, you should start a new thread but you can, of course, say "In another thread, a user said "XXXX" and I would like to know ...". You can quote the relevant part of the other post or provide a link to it but it gets very confusing when someone asks a question and then, halfway through their thread, people start answering a different question posted by a different user.
