I just edited a toot because I very belatedly realised that I'd forgotten the #AltText.

I normally remember myself, but not always, it seems. I think I've seen mention of a bot you can subscribe to that taps you on the shoulder at the time of posting and tells you to include an image description? If anyone can point me in the right direction here, please, I would appreciate it.

Edit to say: thank you! I have now followed @alt_text
