Doing a favour to English native speakers...
Ziu, everybody here is giving reasons except you. After reading the whole topic, I still don't get if you want some sort of forever-alone Spanish forum here or what.
Every Spanish speaker involved with eAthena is already in DivineRO, whether you like it or not, you have to accept this. Otherwise, please tell us where are they. If a new forum is created here, I don't really know who's going to be asking for Spanish help in this site, all the FAQs, Guides, Materials, etc are already posted in DivineRO. The whole community of Spanish people is there... come on. Unless you force them to move all the materials, nobody is going to come here... (and you can't do that)
Most of the Spanish speakers who posted in this section got to know of this site thanks to DivineRo's link. eAthena will not loose active spanish users because it never had one.
I expect you'll think about the situation and change your mind.
