Upgrading to IPS4 was a huge step forward for Invite Scene and long overdue, even. Site administration and moderators worked tirelessly to ensure that any applications / hooks (plugins) that were being used on the 3.4 edition of Invite Scene were available for IPS4 or at the very least, had a reasonable alternative. Invite Scene did leave a few features behind but nothing we couldn't do without for the sake of continuing to provide a stellar and valuable service to its community.
