Option to choose second prefix for thread title is needed. Look at this topic it has 2 prefixes (Add-on & Paid) Essentially we just need to duplicate prefix wherever it appears but with their individual settings: * Visibility for forums and groups of users (the same rights system that we use for original prefix) * We need an option to set select of prefix as required = force users to use it. This add-on may be coded based on Multiprefix add-on, we have a license for it. But Multiprefix doesn't fit our needs for these reasons: * Impossible to set different prefixes from different groups (one prefix from group 1, the other - from group 2) * Impossible to set 1 of prefixes as required and other one as optional. As far as I see it, it's needed to duplicate code for prefix, so it should appear in thread's title and admin panel's settings. Please offer your prices for this work. On pictures below I tried to show you how it should looks like.
