1) Just Now: {Sheesh}
I began an explanation of above Test/multiple-posts, went back to look at my text; returned -- Sys had eaten my new text. Repeated with garbage text: same result. Sys has broken hippocampus module?

2) Initially, I had merely typed in the (complete) URL for worse.com
Saved.
Was not in linky form - just text.
Tried the <a href drill, after deleting the bare URL
No joy - both still text format.
Then I just added bare URL.
Saved:
It made a link! (also linky-ified the contained addy inside href ...)
Then I added my comments and saved again.

So.. not a real problem, unless having to try twice? means anything at all.

Maybe 1) Is a bug?
I'll try on some other post and see if the text vanishes, after a backspace, fwd-space.
