Although regretably I don't have as much free time to contribute as I once did, thus limiting my own input, the Silmarillion section was, and still is, my favourite section. When I first joined here almost seven years ago, a lot of the members were only reading the Silmarillion for their first time. Back then I was able to help a lot of them to understand better some of the concepts of the book, which for a first time reader can be a difficult book to follow. As time progressed, I was able see several of those people become experts themselves, and now some of them have a far better comprehension of the story than myself.
Unfortunately, as replying to discussion topics about the Silmarillion frequently requires a fair bit of research to back up your view, I find it is one of the sections I now have trouble finding the time to actively participate in. Not to worry though... I've left the section in safe hands. Virumor, Gandalf Olorin and several others have surpassed my own knowledge and now hold the crown ;)
