Well, I'm the troll-provoker.
I must have done something wrong to have provoked two reaped abusive replies (out of only three direct replies so far.) I'm still a bit confused, but I think it's partly because I posted a long node without using <readmore> tags. That's fixed now, I hope.
I'm pretty new here, and just starting to find my way around. If I'm doing something wrong, I'd like to know about it so that I can stop doing it. Obviously I'd prefer not to get anonymously flamed, but I don't think I need to say that ;-)
For the most part I've felt very welcome here - many thanks.
