Are there any features you didn't know existed for a long time but that you now really enjoy?
There are a few that I knew existed (of course) but didn't get accustomed to using until a long time later like Viewing new posts or the buttons to make vB code quickly. Now I only use those to create links. We also have a few custom codes like [DICTIONARY]dictionary[/DICTIONARY] where a link to the dictionary definition of a word will be displayed automatically.
The Table button will Center some text
The CIMG button will put an image in the center
Now that we've split out Wedding Talk I've bookmarked "All" Day's Posts so that with one click I can get to the day's posts for DT & WT in one place.
If you have a slow connection and don't need signatures or avatars, you can disable them from that page also.
Same here Horizon. I love that and the "All New Posts" button at the top. This way I rarely miss a thread. I LOVE IT it makes it so easy so that your not jumping from one board to the other. I never understood why peple were bumping threads that were just one or two lines down from the top - now I get it
