It's also interesting to think that it might have a symbiotic relationship with this website... this website is the official discussion place for entries on Dhamma Wiki, and potentially ideas for more subject matter might come from discussion at Dhamma Wheel.
You might want to send a link to Dhamma Wiki to the owner of this Theravada Search Engine - http://s.billard.free.fr/dhamma/
as it would fit in perfectly there.
"Do not force others, including children, by any means whatsoever, to adopt your views, whether by authority, threat, money, propaganda, or even education." - Ven. Thich Nhat Hanh
"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
