I thought that was the way it worked at one time?
In threads 6.5.x you had one membertitle. Could be post-based, but you could also put custom stuff in it if you wanted. We used it for custom titles.
In 7.x, you had 2 seperate items. The post-counter based one, and a custom one. The ubb 6.5.x titles were imported in the post-counter based one.
If you would set a title with 7.x after an import in the edit members section, you would get 2 membertitles under a name.
Before version 7.2, ubb would check if a user reached a certain post count, and if so, update the membertitle with a new post-based one. Since version 7.2, the post-based membertitle is forced with every post a user makes.
Since we had all our custom titles still in the post-based title field, this gave us a problem.
