I have been using phpBB for years and am strongly considering switching to xenForo. 1. Is it possible to put my own custom html/css at header and footer (outside of forum)? We have a custom header and footer which matched the rest of our site and would like to have the forum between these. Is this a complicated thing to do, or is it a matter of editing some template files? 2. Right now I have two installations of phpBB on one domain. One is a public forum and one is a paid/private forum. Users in private site have accounts in both forums. Users only in public forums only have account in public forums, and cannot see profiles/interact with users of private forums (except through the profiles in public forums). All access permissions are controlled by aMember (membership script). And users who have accounts in both forums have only one account in aMember. Single sign-on exists through aMember. All users sign in through aMember. Users can navigate from one forum to another while remaining logged in. Is it possible, and if so, what would I need to do to set up this type of configuration with xenForo? Would I need to buy two separate xenForo installations? Would the "XenCentral Multisite System" provide this capability without having to purchase two separate installations? I know aMember has an integration plugin for xenForo (they use this forums script on their own site, but I'm not sure about he rest. 3. When importing from phpBB, I'm tryig to understand how this will work and if it's even possible with our configuration. For example, after import, will it be possible to keep xenForo users synced to aMember accounts? Thank you for any clarification.
