The "clicking on the title" takes you to the first page. That is part of the software and not something I am inclined to "hack". It is possible that the newer version of UBB takes this into account. I haven't had the op to go and see what new bells and whistles they have added since my last update.I prefer a linear approach to bulletin boards. I personally find it difficult to read "backwards"... latest post first and have to go backward to the very beginning to find out what is going on. Just a personal preference. I really hate it when people do this in an email. 
I fully understand the issues surrounding dial-up access and on occasion suffer with everyone else who doesn't have a substantial pipe to travel along. I am lucky if at home I can manage to squeeze 48 out of my modem. Believe me, I know what SLOW is... to date myself... try AOL c 1989 on a 2400 baud modem. The old timers will know what I am talking about.
I don't think there is an easy answer as to how to best deal with this issue. It occasionally happens when someone doesn't check the first post date (not a big deal). We've seen a lot of thread re-activation lately and in some cases this has been good.
Most of the boards I have been on go with the default setting and list the start of the thread first. So to find one going in the other direction is not the 'norm' in my experience. To change ours, I feel the need to quote TREK and say "the needs of the many..." However, if the FS community would like to see it go the other way I will entertain thoughts on this...
