Is there some place where older builds/versions can be downloaded from? I need the IM plugin version 1.0.
I’m not too sure where this plugin currently resides. But SVN access for the version 1.0 source can be accessed via SVN at http://svn.igniterealtime.org/svn/repos/gateway/tags/gateway_1_0/ You could then use ANT to build the plugin.
Hope it helps
