One thing that worries me about the switch to new forum software is breaking existing URL links to articles. For example, here is a link to a useful thread that is a collection of the most informative threads about taxes:
http://forumserver.twoplustwo.com/sh...Number=4712394
Both this link, and the links in the thread itself, may break if special care is not taken during the upgrade. Aside from links within 2+2, there are many valuable external sites that refer to the best 2+2 posts with URLs like the one above.
It would be a shame to lose all of this. It's part of what makes the web great.
