If you've been using the board style subsilver2, you may be surprised to see how the board looks now. With the software upgrade last September, ProSilver became the new default for phpBB boards, but Kernos retained subsilver2 as our default because so many people used it. As new updates are released and installed, more and more things happen and it got to the point where having subsilver 2 as the default made the "Submit" button on the registration page disappear! Obviously this had to be corrected, so he changed the default style to ProSilver so people can again register for the board.
Some of you are probably saying, "I hate this! Can I have my old one back?" Answer: Yes...as of now, at least. Go into your User Control Panel and open Board Preferences. You'll find a drop-down for styles and you can pick the one you want. However, we don't know how long we can keep subsilver2 compatible with the board, so you might consider trying ProSilver for awhile to see how you like it. I made the switch when we did the upgrade 8 months ago and I find that I like ProSilver much better than I did subsilver.
Anyway, that's the story. Sorry for any effects it caused!
