This content still holds true for a older version of Electrum wallet and it might be needed by Users of older versions of Electrum.
However, the new Version now supports an Automatic RBF inclusion for every transaction made so there's always a chance to replace or simply Bump transaction fee if the need arises for all Electrum Wallet Users
Updated to say that opt in RBF is always on.
Can my name please be removed from the OP? I have not been able to help with stuck transactions for years and still receive messages asking for help
Done. Updated that section in general to point to the services rather than to specific people.
