Quick Tip: Searching for Username
Use the advanced search, which you can access by clicking the "search" button in the top middle of every page. Then click "advanced". When the box drops down, enter the user name (make sure there's no text in any of the other search boxes), and then click the "search" button (not the one at the top of the page).
Once the site gets going, it will be better. For now, it's hard to see which of my posts might have had some responses on the old board without checking them out first.
Also, it would be nice to see when first looking at a topic who's responded, as sometimes the responder is someone I take seriously and will look at his or her posts (yes I know I can bookmark but before the names would just jump out at me) - maybe a schematic tree of some kind as a sidebar.
