I admit I don't fully understand the tagging system, but we seem to have 'wallet' and 'e-wallet' tagged as synonyms. They have nothing whatsoever to do with each other. The tag 'wallet' is for questions about the Bitcoin wallet system used by the client, or at least that's what its description says. Whereas 'e-wallet' is the name used for services that provide you a notional wallet with a web-based (or text message or whatever) front end.
Is this just an error? How can it be corrected?
