That is certainly a great idea! Ohoh... English fan mysteries, that'd be great.
Also (I guess this is a bit late), but thank you so much Nadeor for volunteering to translate EPX and everything. I can imagine how that would take a terribly long amount of time. But, on the other hand, I'd really love a translation of that other fanfiction you mentioned. Of course, we'll give you an infinite amount of time to translate it, won't we?
