Is it possible to configure the default welcome message Echo gives you? Currently it always says "Welcome to {{{SITENAME}}}, {{{NAME}}}! We're glad you're here." I'd like to be able to change it to include a link to the rules and the f.a.q. The ideal way to do this would probably be to use something like Extension:HAWelcome or Extension:NewUserMessage but since I'm using Structured Discussions/Flow neither of those work.
I've been trying to find the PHP file that generates the message to edit it directly, but no luck yet
