15:20:59 < ekem> fine.

Do we want !tell functionality? If so, let's make it as non-spammy as possible:

• Private message the person next time they're seen in channel
• Assume it's the same person if they have a nick which differs only by punctuation (so vanryss ~= vanryss_ ~= vanr1ss)
• If they're absent more than a given time since being told, the PM should include what they asked, ie

Hamper: When you were last in <room>, on <date>, you said <last thing they said>
Hamper: After you left, <nick> asked me to tell you <message> when you got back.

That'd be a fun plugin to write. A small Levenshtein distance on lower case nicks would probably do the trick. One concern, hamper would need to keep track of the last thing said by everyone in all channels, that could add up to quite a number of rows quickly which is an issue for the free Heroku tier being used for hamper currently.

Unless !tell works on a short log instead of all time, then a single row per channel could be used possibly.

Hamper is already keeping track of the last... 20? messages per channel. It probably makes sense to also keep track of the last message everyone sent in memory. This probably shouldn't be stored in the DB.
