All very good advice especially the dratted !!!s and the last point you made about the internal runtimes. V4.1 is the only character I have come across so far that HAS to be in the main runtime. Pyton scripts and stuff need to be in there too of course.

I think e frontier/smith micro should create a complete new runtime system for Poser 8. They could leave the old system still operational for old content but they should create a system for installation of new content that worked from within Poser that prescribes the locations of content files and enforces a better structure. An automatic mechanism for exporting content in the new format would be good too. Finally they really NEED to come up with a mechanism for preventing unauthorised file sharing - something like a centralised certificate server to check the validity of embedded certificates. So much file sharing goes on.. It just means prices are high and that just encourages more sharing.
