I just got MyBB and it seems way better than IPB and phpBB. I don't know how to install the portal. I will give you a link to my forum if needed.
Well you have a portal already - ./portal.php. You can install some external portal system if you want (for example Joomla) but this isn't the forum to discuss that AFAIK.
OK. I will look for that in my FTP. Thanks.
OK, but how can you make it so you'll be taken to portal.php instead of index.php?
There are many threads on this, try searching.
