Thank you for the feedback, zmoreira. It is very much appreciated.
1) Unlike in many other forums, in bbPress the recent discussions are prominently featured at the top of the main page, which largely eliminates the problems of having many forums while the community is still small. I seriously considered limiting the amount of forums during the early stages, but ultimately decided against because I know that once the community grows larger and requires more forums, I would then have to manually shift all the prior topics to their respective more-specific forums.
2) The color scheme is from the bbPress "Options" template, I didn't make any significant changes to it (the reason I chose this template is because they have a functioning header menu, which would otherwise require a lot of coding). Re- the colors, I could edit the style.css file to make it lighter and more consistent with the look of the blog - and I do plan to do this eventually - but it would take some time, several hours I could otherwise devote to the blog or book.
I am somewhat surprised that you find this color pattern difficult to read, since the contrast between white text and dark background is quite marked. I will keep this complaint in mind however, and would also like to take the opportunity to inquire as to whether other readers also find the visual format, white text on dark background, unpleasing? Should there be a significant demand for change to the more conventional dark text on light background format, I will put redesigning the forum further up on my list of priorities.
Again, thanks for the constructive criticism.
