I am using Windows 8.1, Google Chrome Version 33.0.1750.154 m.
As the LCL Team appeared to ready the forum area "4 - Peers" for today's session, I found myself temporarily unable to create new topics. I tried replying as a new topic as well as creating a new topic from within a forum (i.e., this "About this Forum" area). For several minutes and for multiple instances, the topic dropdown woud not show any options for forums that I could select. It only had "Select a category" listed and nothing else.
I closed the tab, waited a few minutes, and tried again and now it seems fixed. Just a heads up in the slim chance it is a previously unknown issue or this report yields new information towards a solution.
