First of all, congrats on adding Xen Gallery. I think it's a good call. Nice product. My suggestion isn't specific, but I run a community for older women and they often have trouble using the gallery because it's clearly laid out by a programmer and not a designer. The flow of how to add new media and interact with current media is not all that easyobvious for them. Again I don't have specifics, but just imagine if the software was released as a solo product like pinterest. Many won't agree with me, but that is because you are problem solving programmers. I just go by what I hear and that is my older women community who can use xenforo fine, sometimes have trouble with figuring out the gallery. thanks!!
