I like the layout as it is as it is different from most boards. I can appreciate that the images for the individual make the main page somewhat long and can sometimes make loading time slower, especially if you use dial-up. 🙂
You could possibly create smaller icons or buttons for each season so they would
a)Take up less room on the main page and
b)Load relatively quickly
Or you could have 3 images which are slightly smaller than the season images at present, on the front for Angel Seasons, Buffy Seasons and Tru Calling, so all 3 shows are prominent on the main page but you still are taking up less space and creating a shorter loading time. (I know no-one as yet has mentioned loading time but it never hurts to consider all the benefits). In the Angel & Buffy seasons you could then still keep all the seasons individual.🙂
