I made a post on the saitom box topic suggesting this after people said they couldn't make the dates or didn't know.
It would be great to have an opt-in newsletter. I want to be kept informed of things like site changes, newly added content, new books or artists, merchandise, exclusive content (see point below).
The point is to keep people who want it be informed. As a publisher you'll reach more people and grow your business as more and more people sign up. I know I will, I want to be kept up to date. Plus if a limited release is properly announced 2-3 weeks early I can plan beforehand to be free.
Also, what if artists did works specifically for FAKKU? Maybe small chapter or doujin release but as the site grows there can be magazine/book releases? That would doubly entice me to get a newsletter :P
Anyway, what do you think? Thanks and keep it up!
