The RPSI (or for that matter, the DCDR or ITG) will willingly co-operate, as it were, with anyone... However, the issue inevitably is that the "preservation equation" comes into play:
Low Volunteer Numbers + Barely Adequate Finances* + Tiny Enthusiast Market in Ireland = Run What You Can Manage To Turn Out.**
* Lower public market than in, say GB; less grants post-recession - not that any organisation can rely on grants to survive, no financially viable enthusiast market, high operational costs.
**. Rather than what us enthusiasts might like in an ideal world!
