I've added preliminary support for tagging stories with short tags. I've also gone through all my stories and tagged them. For example, here's a story I posted about my Sharp MZ-80K: https://twostopbits.com/item?id=16

I've tagged it with the tags sharp, z80 and mz80k. The rules for tags are as follows:

1. Each story can have up to 8 tags (although I think fewer > greater).

2. Each tag can be 16 characters long.

3. A tag can only consist of letters and numbers.

4. Tags are entered space-separated (e.g. sharp z80 mz80k)

You can click on a tag to see all the stories tagged like that. For example, all z80 stories are at https://twostopbits.com/tag?q=z80. You can see a list of known tags on the submit page. Feel free to use them and add your own.

Lastly, keep tags short. It's better to tag something n64 instead of nintendo64 (but feel free to tag the same story as nintendo).

I've also given everyone extended edit privileges to their own stories so they can go back and add tags. Tag away!

(And, yes, the next bit of hacking is to make the site useable on mobile!)
