Module SVN Up info
8.4 and up
Just assign the module, and users will see what version the Tiki is.
If everything set up correctly it shows a line such as:
Last update from SVN(4.1): Monday 21 December, 2009 07:05:20 UTC - REV 23971
If something like v8.0beta (SVN) suffices you can use the version option of the module poweredby.
