Not too late if you can manage to get it to the relevant office in time. I didn't post mine, it was hand delivered to the council offices at the bottom of Ormerod Street.
On the point of the requirement for a witnesses signature meaning this isn't a secret ballot ------ the paper is perforated and meant to be detached. All the witness is witnessing is your signature on that particular piece, not your vote on the other part. They have to be separated to put in the different envelopes anyway. (ballot paper into inner envelope, witness paper into outer envelope along with inner envelope)
I prefer "live" voting too - at least that way I actually remembered to go and do it. I kept forgetting to fill this flipping form in.
