Why am I unable to select some of the S2 styles?
The Boxer and Component styles in S2 are not available to free users. All other S2 styles are available to all users. If you wish to use The Boxer or Component styles, you will have to purchase a paid accounts. For information on paid accounts, please see here: http://www.livejournal.com/support/faqbrowse.bml?faqid=21.
That's it. It's short, but I don't really think anything else could be added. It would probably be best to combine it with another FAQ, but combining it with the "What is S2" FAQ might get a bit... yeah. I don't like the idea of someone having to read through all of that just to find out they can't use it without paying for it. But I don't know. I don't really know anything about FAQs, I just think that it's a great idea for something like this to be added in somewhere, when you lovelies with FAQ edit get time. Whatcha think?
