To create a community, you will need to have one pre-existing personal account and be logged in under this account (http://www.livejournal.com/login.bml). This account will be the maintainer account and all changes to the community will be made via this account as it is not possible to be logged in as a community.Personally, I think this is highly misleading. It sounds to me like you need to create a new personal account which will then be converted to a community. This is how it used to work (I'm sure you all know), and especially to people who know that it used to work this way, this opening paragraph seems to suggest that this is still the way it is done.
Personally, I don't think the FAQ should stress so much that you need a maintainer account. I think it is highly unlikely that someone would want to create a community account if they don't even have a personal account.
Hence, my suggestion would be to remove this opening paragraph and instead just write:
To create a community, you will first of all need to be logged in to your personal account.Then, perhaps later in the FAQ, one should mention something like:
Your personal account (that you were logged in as during the process) will then be associated with the community as the "maintainer account". You will need to be logged in to this account whenever you want to change something about the community, such as adding users as members (http://www.livejournal.com/support/faqbrowse.bml?faqid=80) or banning someone (http://www.livejournal.com/support/faqbrowse.bml?faqid=84). If, some time in the future, you would like to hand the community over to a new maintainer, please refer to the FAQ at http://www.livejournal.com/support/faqbrowse.bml?faqid=100.
