Thanks, David! I find the immunology articles quite interesting,if only I could understand all they say...
You've asked alot of tough questions in your post down below. I haven't had the time this weekend to try and look at anything, but if you can give me a bit (could take a while), I'll try and dig up whatever I can and post here anything of relevance. But as 'willing' said, at this point in time there may not be alot in the way of definitive answers to many of them.

if the thread has not reached the 50th comment, you should be able to continue the back and forth until it reaches that number. The forum gets from 6 to 8 new threads a day, and if someone clicks on post a question and does not use it, that slot gets lost for the day. That does not seem to happen with the post a comment button. It is best to utilize existing threads to the maximum, since the threads are so limited.
If you have a question, do not wait until you can open a thread, it might take you forever, better to post it in a current thread and in the 'to" field titled it, to call attention to it.
you should be able to just "post a comment" below in the same thread, kindof like a conversation going back and forth... each thread has usually 35-40 comments, and we are only allowed so many threads a day. We all hijack threads when it seems like the topic is covered, or if we have a burning comment, or well just feel the need to express. I have also heard you are limited on the number of new threads an individual can start, but I haven't seen any evidence of that..
