if I may offer a few pointers for you from my own experiences with visiting and logging into boards?
I suggest you do NOT have a board with an interface such as
http://z11.invisionfree.com/SevenDeadlySin...dex.php?act=idxI was recently ON a board like that ; and left pretty sharpish;for starters I found I could not see what I was typing on the screan which was hidden in darkness
the board needs to be light and inviting, easily 'read';
if you wish to 'fund' it with ads such as some forums do you need to be very careful of what ads you DO allow; one forum I am on is really only 'readable' when ALL the intrusive ads are blocked
as for topics etc, you can alwasy expand ON the topics once you have gotten started and get feeback from the staff and members
