Out of curiosity, are you open to having traditional scrappers here? Or is your plan to keep it just digi? My mom is a paper scrapper and she's been enjoying the online community recently (I think she's been hanging out at CK the most). I think she'd really like it here but I wasn't sure what your vision was along those lines.
As a side note, let me say it's really cool to share the same hobby with your mom.
It's great bonding time. We're always emailing each other about cool scrappy sites and talking about our layout plans and scrapbooking stuff in general. You know, I'm gonna have to do a layout about that soon!
