It really depends on the content of the website. If it just has articles, decklists and comes across as a fans website i wouldn't foresee any problem (I could be wrong - but i don't think that this site or Cobra cards or other sites have Decipher approval). At the same time, if the website offers nothing new that TLHH already offers what is the point of creating it.
The issue is if the website states or does things that need approval from Decipher. Things that might be an issue include modifying cards, issuing v-cards, modifying rules, issuing an up-to-date CRD, etc. None of those things should be in place or even mentioned on the new website when it is launched. If they are, the site is travelling of dangerous grounds.
Decipher has contacted TheJord and said they would consider a LOTR PC, but not before April this year. That time has arrived, but nothing is in place as far as organisation and overall leadership. Until that happens, there is probably no point contacting Decipher.
Just my 2 cents.
