I encourage you to learn the basics, common etiquette for volunteers, obtain the appropriate status then move onto edit.
You have been in her shoes too, and it took you to memory lane because both of you want/wanted to help by improving the English subtitles (I remember those days too). You say she should learn the basics? Why not suggest some of the basic to her from your own experience?
Common etiquette for volunteers? Why not suggest links that can help her explore those etiquettes you feel a volunteer here need so much to edit an English subtitle?
Obtain the appropriate status? That is; if she EVER gets the chance to move on and be part of a team since we have a ‘‘buddy system’’ here, that closes doors for many with bigger and better skills but are never given a chance to show their full potential.
YES, good luck @kimanjo_519… you ‘‘gonna’’ needed if you ever want to edit any work (sub) here. Don’t worry about before a TE, GE, or CE since some say they are so great, and leave a lot to desire in their ‘‘editing jobs.’’
It will help if you can elaborate more on your experience as an editor. Look at it as a ‘‘resume’’ the more you show your expertise, the more appealing you become as a future editor for this so wonderful site. Break a leg (I know it’s good luck for theaters lol).
