now whent it comes to asking about using pprune, then let me as well to ask two things.
1- How do you see if there are new replies posted in the threads you have posted. apart from subscribing e-mail notifications and advance search? or how do you see all the threads you have posted?
2- how do you subscribe to a thread without posting in it? I mean just to keep track of a thread without really posting because I see the subscribe commands when you only hit the reply button in a thread.
