The Englisc List Website—A Forum for Composition in Old English is a treasure trove of material for people who want to use Old English, not just make their way through Beowulf with a glossary.
While some discussion is conducted in Old English, a lot of it is not; but activity on this list aims primarily to: 1) compose a message or an original text in Old English, 2) translate a modern or medieval text into Old English, 3) participate in ongoing projects devoted to the above, 4) comment on the contributions, 5) offer something new, 6) pose questions about grammar and vocabulary, 7) be tremendously entertaining while remaining relevant, or 8) just lurk and learn.
I particularly like the New Anglo-Saxon Chronicle, whose most recent entry reads:
[Anno MMIV Hreðmonað]
- xix d: Ymb þisne dæg ymb Wala ceastre in Suð-Waziristan provinciam in Pakistane Pakistanes fyrd fohte wið beorgweargum ond Bin Ladenes heafodþegne, ond neah in Afghnistane Americisce fuhton wið Talibaniscum.
