Always feel welcome to contribute sfetter. Keeping things organized is just housekeeping.
If you want to take a moment before starting a new thread, you can use the "search" function or the "show unread posts since your last visit" function to get a cursory look at whether the topic you intend to post is already here. But in the event that you don't, or even if you do and miss something, it is no real bother to merge threads. That's part of why we're here.
Thanks Teach and Pan.
