/************************************************************************
 * Forums / Channels.
 *
 * The existing experiences of Forums & Channels have highlighted some
 * significant limitations of the Cache-Based exchange system. The new
 * and improved system will be based on GMXP.
 *
 * Existing Issues to deal with:
 * 1) GPG Signatures take too long to verify (GPGme/gpg.exe issue)
 * 2) Signatures are re-verified each startup.
 * 3) Forum Messages are broadcast to all peers - excessive traffic/disk space.
 * 4) Impossible to Edit Messages, or Comment on Channel Posts.
 *
 * Most of these issues (1-3) will be dealt with via GMXP GIXP system
 *
 * The data structures below are closely modelled on existing types.
