On the same vein of the question about dndtools. Realmhelps.net too have complete description of non-OGL item.
This time the scope of use is way smaller, we have only 39 istances where the site is used, in both questions(15) and answers(24).
While probably the site won't be closed soon (Wotc have moved on from 3.5 and, as far as I can tell, they are not striking any of the new dndtools clones), I think, for coherence at least, we shouldn't make use of the site.
