To receive extension support please visit our Extensions Database
and post in the specific extension’s designated support area. The link to the support area for each released extension is also available in the first post of each released extension listed in the [3.1.x] Extension Database Releases
forum. For extensions still in development (not recommended for a live board) support is from that extensions's topic in the [3.1.x] Extensions in Development
No support is available here for extensions not obtained from this site or for extensions marked as abandoned.
For the second question have a look in the Extensions Database
. If you can't find one that is suitable you could look in [3.1.x] Extensions in Development
, but note that extensions in development are not intended for a live board. If there is nothing there that suits your purpose you could post in [3.1.x] Extension Requests
BTW - there are no threads in phpBB, they are topics.
