If you are using a mobile device, it can be bit hard to navigate. If possible I suggest accessing the site from a laptop or desk top computer and learn your way around and then you will have a better idea of where you are on the mobile device.
The good news is that the site will at some point be updating to a newer version of IP board when that becomes finalized and hopefully, the changes will make browsing across devices a bit simpler.
If you are looking for a particular story or author, I'd use the search, but you have to use the pull down menu to the right of search to specify the search you want to make otherwise it defaults to a Google web search which can display a ton of stuff from across the web and not just the GayAuthors site.
One last bit of advice. Use the Google Chrome browser to access the site as it seems to work the best, at least in my humble opinion.
