Your DoughWallet and your /u/sodogetip will have different addresses.
Folks here will tip to your sodogetip address and you can tip out from it, too.
You can transfer coins from your sodogetip address to your doighwallet address at any time.
Send a private message to /u/sodogetip with “+help” and you will get all the info you need to pass coins around and withdraw them.
Also, I would recommend a personal wallet with a different service like DogeChain.
Merry Christmas!!
