- Hire a prof QA to do it quickly and efficiently.
This so much.
I finally got ET installed and it's quite horrible. There's a bunch of issues reported on Github but unfortunately I don't have time to go through all that and figure out what's already been reported, what has been deemed as acceptable etc. There needs to be a somewhat dedicated person with QA experience for testing it if there isn't one already. Random users poking around won't cut it.
