How do I go about it with an ETH address? Is that also sufficient? Can I just use MyEtherWallet and create a message similar to the one Theymos asks for when it comes to proving ownership for BTC addresses?

As far as I know, signing ETH address is not accepted method of proving the account ownership, and only signed BTC address is accepted, as mentioned by theymos in Recovering hacked/lost accounts .

Looks like that there are some issues with that, as explained by @pooya87

it is not just about this being a "Bitcoin forum", the problem is the lack of a trusted wallet to do the signing and verifying of signatures and also whether the person verifying has that wallet installed. otherwise the processes are the same. bitcoin uses secp256k1 curve while ethereum uses secp256r1 curve with only different constants but same size signature and same EC calculations.
