I know this has been mentioned several times before, and I have been waiting for an upgrade to this archaic software for over 4 years now. phpBB 3 is currently in Beta (which is something I suppose) and looks likely to hit RC stage within the next few months.
If it does hit RC by then, I might just convert this forum over if it works (I have tried with a beta, just got a cryptic error message).
Might just pep this place up a little, who knows
