It would be something very new and cool letting members create a post on the community via free texts. Like I want to create a post in the help and support section so I text the word new to 43435, for example....
I'll get a text back asking me the subject/title and an another one asking for the post content
Then it will be asked "do you want answers get texted directly to you?
So Giffgaff can advertise "Text support with 90s time for answer guaranteed"
