Thank you for the reply! Do these forum posts ever get deleted is what I'm wondering? I'm wondering if it's a good idea to host many decks directly from a forum post like this or if it will just end up deleted automatically.
Wwolfe is correct. They rarely get deleted, unless it breaches the rules as outlined in each forum directory.
I don't see the need to create a running topic for your EDH decks,
Your decks can be saved to your account, as you can create them. You can see them via your {USERNAME} on the top right-hand corner. You can even catalogue them into sub folders, if you wish.
