Recently we installed the plugin "Topic Solved" for phpBB, and you can mark as "Solved" by our tool, rather than manually modifying the title.
This mod is activated only at the forum set "Questions and Answers".
If your problem is solved, please check to the reply which solves your problem on the top-right side:
In this way, others can see that your problem is solved and reply to other problems faster, and users who has the same issue can find the solution faster and prevent from asking the same question.
In addition, this program is not translated in most of the languages available in this forum, if you can help us, feel free to post here:
