By no means! People with any amount of Tolkien "lore" are welcome
to participate. It is advisable, however, to have read _The Hobbit_
and _The Lord of the Rings_ before spending much time here, as

When you do participate in discussions, just use whatever Tolkien
knowledge you have: you can have great ideas regardless of how much
you've read. Occasionally, others will cite sources (often obscure but
just as often authoritative) that weaken or disprove your arguments.
When this happens (as it does to every one of us), nobody will think
less of you for not knowing the reference; treat it as a chance to
learn something new about Middle-earth.
