Make sure that the following option is checked:
Plus! > Preferences > Instant Messages > Commands & Tags > Allow the use of commands and tags
Also, tags must always be uppercased and enclosed in brackets. So it's not
!ver, but
(!VER) that you must use... For plugins this is just the same: not
!xthetag, but
(!XTHETAG)... (Plugin tags and commands always begin with
x).
A complete list of all the standard MsgPlus tags and commands can be found here:
http://www.msgplus.net/help_cmdtag.php
A list of the tags and commands of a particular plugin can often (should) be found in the readme or instructionfile of that plugin or by going to the menu
Plus! > Plugins > pluginname > ....
