Can you add a tempmute timer, which expires only when player online??
When moderator muted some player for 24 hour, and that player 24 hour dont be online, that punish for him don't have any sense!
Maybe u can add individual command for online-expires-tempmute, or something like additional flag to command ??
/tempmute - usual tempmute command
/tempmute -oe - tempmute command with online expires timer

And one more: I thank you for this plugin, but did you will to fix someday that f*cking bug with UUID?? In my server only 10% players have mojang accounts. What should i do??

Duplicate of #211

As for the UUID issue, it's a problem down at the Bukkit side, it is case sensitive when generating UUIDs. The solution, run an online mode server, or feel free to make a pull request with a fix.

But why your plugin can't just use another mode, and give ban for players by their nicknames?? (for offline-mode servers)

I don't officially support offline mode servers on principal. Basic offline support mode was added through a pull request, and I'd much rather work on new features than attempt to support a very legally grey area subset of servers.

Sure you're right, noone dont like piracy... But when peoples barely have salary - 120eur, Not everyone wants to give 20e for the game...

So, maybe u can fix that at request ??
And which price ?

If I understood correctly, that bug happen only when player join first time with one nickname, and second time with the same nickname, but with another case?? And then BM can't check this acc??

Unfortunately @confuser does not do any paid coding. See #373

With IpBan this bug with UUID is not happen, right?
Maybe u can add Temp-Ip-Mute and Temp-Ip-Warn at least ??

Please, say me when specifically this bug is happens? In which circumstances ??

Why don't you use a different banning solution? BanManager is obviously not suited for your needs, there are lots of other plugins out there.
Also, using IPBans is not recommended, as most people have dynamic ips.

I have tried a lot of Ban-plugins and only BM meets all my needs ;[

As written above offline mode support is not directly supported so you may ask the author of this particular plugin of this would solve your problems.
