Did I understand you correctly?
You can click the buttons ‘go top’ or ‘go bottom’ if the thread has just one page, or you can click the number [1] at the top of the thread…
Say you look for postings about ‘freezing’. The result of this search is a list 48 postings numbered 1 to 48. Each posting has two links pointing to the author info, a ‘reply’, ‘quote’ and 'notify button. I do not see a ‘go top’ nor a ‘go bottom’ button. I have no way to click on a posting in order to see the complete thread.
Oh, I see…
You can click at the name of the thread and, after, the buttons [1], go top, go bottom…
I think there is not a button to avoid one mouse click… :-\
Technical, I agree with guivho. Many forums indent or number replys so they are directly attritbutable to the post to which they are responding. e.g.:
Question
Reply1
Reply2
Reply to Reply2
Reply3
Reply to Reply3
Since some replys are to replys rather than the original question, using only sequential numbering of replys is somewhat confusing unless the reply includes a quote from the message to which it is replying.
