She will be remembered
I've read The Register for well over 10 years, and have never sent any feedback nor made any comment before, but I wanted to today after hearing the news.
Like many I'm sure, I was enraptured by Ms Sladen's portrayal of Sarah Jane Smith as a boy, and I was very pleased to see her involved in the new Doctor Who. It's very sad that she died before what we now expect our time to be, and I extend my sympathies to her family. I'm glad she is imortalised in the fabric Doctor Who which has a unique place in British Culture.
I hope the BBC dedicates the upcoming Doctor Who episode to her, and though I always have the remote control ready to turn away from the spoiler at the end, I will make an exception this time if needed.
