I'd love to do some testing as I have quite a knack for detail and when I used to do programming would often do well with various test cases. In either case, a couple of suggestions that I'm hoping might already be in the works: when you log in to have it remember you on trusted devices. I hate when I see a link to new content somewhere and I have to log in again if I haven't been on the site in say a few hours or so, and it gets a bit annoying. I know it seems small but it's actually one of my biggest pet peeves with the site as a member.
I'd also suggest since you want to reduce categories to keep a sort of media section with audio, video and pictures. With a title like gallery I'd assume it's only pictures, and I see on the screenshot it actually also includes video. A simple renaming of the section might work, and then just add an audio section (ie the current category is better). It'd be pretty cool if this section also automatically pulled any media from blog posts (pictures, audio or video). And the Hanson Time Podcasts would be in the audio section, along with music, reporter interviews, etc. Ideally members could listen to the members EPs here digitally (or at least we could get the new one as a digital download instead of or in addition to a physical CD).
The store: a small detail would be to have the store save cart content and/or have the option to add items to wishlists. Another useful feature would be to be able to buy stuff for others, including membership (either by entering their username when purchasing or by having gift cards).NNot to have to pick the color on an item even when there's only 1 available. To be able to search the store, and to have tags like "members-only" or "HDay" or "vinyl" etc.
I hope this is useful/helpful! :)
