I was running the open sourced phpBB platform for our Discussions. Unfortunately some spam was attacked and lost the access and data too.
Now I would like to switch to the paid platforms and short listed to XenForo.
I would like to clarify few issues before I go for it.
1. What are the server/system requirements?
2. Can I register a new URL and upload this software to it?
3. Is it user friendly to manage?
4. How about spam prevention?
5. Can we take a data backup frequently?
